Armes de fabrication Israelienne - Page 16 Arie

Citation :
In the mid-70s a group of IAI (Israel Air Industries) engineers and IAF (Israeli Air Force) officers began a new project to develop an ultra modern Israeli fighter aircraft – a project that was supposed to take a quantum leap for aeronautics.

Designed to be the most advanced of its kind in the world by any standards, the Arie (Lion), would give the IAF a reliable option to the advanced US F-15 and F-16 types. Although it has never came through, the Arie became the cornerstone of another future and most ambitious project ever, an Israeli breakthrough to develop and produce the Lavi, the Israeli dream aircraft to outmatch the F-16.


Background

In response to the French embargo forced upon Israel after the Six-day warin 1967, a decision was made to strive for independence in the development of major weapons systems. Israel had already acquired the means to build good copies of the French Mirage, but wanted to be much more than just a clone maker.
The commander of the IAF (1982-1987), Gen. Amos Lapidot: said, “The essence was to create a technological infrastructure to develop and manufacture weapons systems in the three major weapons systems platforms – tanks, aircraft and ships. Behind that concept, were three basic rationales: First, Israel should not, and could not rely on foreign countries very volatile foreign policies. Secondly, the Israeli air force always strives to develop and use new war tactics and strategies, and was in constant need of new equipment to fulfill those operational objectives. Third, a national strategy to promote Israel 's and IAI's state-of-the-art technological accomplishments". This last point doesn't come over so well in English - by implication, these accomplishments would deter aggression, save money on expensive foreign weapon imports and maybe help Israeli exports.


Development

In 1974, an IAI team was set up to begin the Arie project. As no government approval had yet been received to produce it, the program was simply codenamed “R&D project”. Ovadia Harrari, who would later become head of the Lavi program, was to lead that endeavor.
The IAI decided to develop the Arie based on the technological knowhow acquired from the Kfir project, particularly from the Kfir-Canard program – the improved version. In fact, the first proposal which was put on hold by the Air Force, was to develop an aircraft to be named “Super Kfir” – a regular Kfir whose original J79 engine was replaced by an F100 model, the same as in early F-15/F-16s versions. That new engine would substantially increase the Super-Kfir's flying performance. However, due to the Air Force's strict specs requirements, a new draft was called for, in spite of the Kfir/Arie's visual similarities.
Over thirty different configurations were evaluated. The IAI tested several engine models, including the British Rolls- Royce RB-199, which powers the European Tornado aircraft. Soon, the options were reduced to just two. The F-100 single engine plane, or a twin-engine version.
The later, codenamed Light Weight Fighter-4 (LWF-4), was to be powered by two General-Electric F-404 engines as used in the F-18. “Looking at the different designs of the Arie, one can notice that it is an extensively modified Kfir” explains Harrari ,“ the aircraft is visually different, but its roots lay in the Kfir”.
The new future fighter aircraft, which was now codenamed “Hadish” (innovative), could be described as a single seat light fighter, capable of reaching 2.4 Mach speed, a 75,000 ft altitude ceiling, with a 480 km combat radius. Armament: would have been a 30-mm cannon and medium range air-to-air missiles. Avionics would include a radar, a helmet sight and an integral electronic warfare system. In addition, the aircraft would have low optical and radar signatures. Even the US F-15 and F-16 could not match these features at that time.
The outstanding question: An air-to-air fighter, or an air-to-ground attack aircraft?
During its initial design phases, the 1973Yom-Kippur war broke out, and the Israeli Air Force focused its attention on the battle proven air-to-air configuration concept, as air power and air superiority consist basically of air-to-air combat missions. Therefore, about 90 percent of the “Hadish” capabilities would be directed for air-to-air combat.


Technologies and Avionics


The Arie had several technological breakthroughs. It was designed to be the first Israeli aircraft to deploy digital fly-by-wire flight control system (at that time, cutting edge technology). This fly-by-wire concept, permitted the engineers to design an aerodynamically non-stable platform. Hence, they could achieve a small and highly maneuverable aircraft.
In the air-to-air version, to cope with enemy intruder aircraft, and keeping its air-superiority capabilities, the Arie would be equipped with advanced avionics and special ordnance systems: a highly sensitive Israeli radar capable of acquiring low-altitude flying targets. Advanced electro-optical systems would enable the Arie to locate ground targets at night.
Another breakthrough, was the pilot's option to use his helmet mounted sight, easing his combat workload. In the mid-70's these systems were nearly unheard of. It would take another ten years for the helmet mounted sight to become operational in any type of combat aircraft.
The Arie's cockpit resembles to a great extent that of the F-16's early versions. Besides the Head-up Display (HUD), a Monochromatic Display was mounted in the cockpit to display the radar's viewpoint.
The Pilot's view was close to 360º visibility– a life and death factor in air combats. This is now the normal design in both Western and Russian combat aircraft from the F-15 onwards.
The Arie's ordnance would include an improved 30-mm DAPA cannon, assorted air-to-air missiles, iron bombs, and precision guided ordnance. Max. military load is: 7 tons.
Although that aircraft was not meant to be a stealth aircraft, some basic stealth features were studied to give it the option to strike heavily fortified missile zones. This objective was based on the lessons learned during and after the 1973 Yom-Kippur war, when Israeli fighters had to face a huge number of SAMs. The Arie would also be equipped with an advanced Electronic-Warfare system produced by Israel , giving the pilot an early warning signal to lock on to enemy threats and jam them.
Studies were made to drastically reduce its radar signature, making it extremely difficult to be detected by enemy radar. For example, its bomb load was to be stowed inside a conformal ventral capsule, to reduce its radar cross section.


A Paper's Lion

According to the program timetable, the Arie's initial development phase should have been completed by mid 1979. Until then, the IAI would have to complete flight tests, select and define all the contractors.
By that year's end, an initial test flight was scheduled for the first of three prototypes.
By mid 1980, 10 pre-production aircrafts should be completed, with regular production to begin in the following two years. The Air Force should be receiving the first production Arie by the end of 1983. Delivery of 100 aircraft would be completed by the end of 1985.
Meanwhile, the IAF was leaning towards the US aircraft option. Rumors indicated that the USA would finally agree to sell Israel F-15s and F-16s. Finally, a decision was made to order the US aircraft. and scrap the Arie.
In August 1975, the IAF's chief, the (late) Gen. Benny Peled released a document defining the IAF's policy in relation to the Arie project. The document recommended the US F-15s and F-16s. Based on his assessment, the IAF began a procurement program of F-15s to be delivered by 1976. Moreover, it had been determined that the F-16 in principle answered Israel 's operational needs for an air superiority aircraft for the 80s. As a result of intense pressure on the IAF, Gen. Benny Peled decided to respond with a letter on May 10, 1976 , stating the reasons not to progress with the Arie: The US would agree to sell Israel F-16s. It had also been agreed that the US would sell Israel the F-100 engine, and there were not sufficient funds to keep the project moving.
“The fundamental knowledge that led to the development of the Lavi relied on the experience acquired from the “Hadish” and Arie”, says Gen. Lapidot, who created the Lavi project board, and commanded the Israeli Air Force by the time the project was canceled. “It can be definitely stated that the Arie, the Nesher and Kfir programs, added significantly to the development of the Israel Aircraft Industry (IAI), so that when we gave the “go ahead” for the Lavi, we already had a complete infrastructure in place and ready to work. In 1980, we decided to build a smaller version of the Arie. It is not by coincidence that it was named the Lavi. Lavi is a Lion (Arie), although a very much younger and smaller one”

Type Single-seat, multi-role aircraft
Max. speed 2.4 Mach

pourquoi petits GDS,c´est un drone pas F15,il n´a pas besoin des tank 1400L pour rallonger,sa cellule embraque deja assez de fuel pour voler longtemps,donc chaque tank qui ajoute du fuel c´est un gain de plus,le nom aussi heavy fuel pourrait venir de la.

regarde fuel tank du Reaper en proprotion

IAI tire avec succès des missiles NIMROD SR transport par hélicoptère  

(Defensa.com) Israël Aerospace Industries (IAI) a complété avec succès une série de démonstrations impressionnantes de tirs de roquettes NIMROD SR (courte portée) à partir d'hélicoptères. La démonstration est composée de 8 lancements de prise de vue, réalisées à des distances allant jusqu'à 10 km et une altitude de 300 à 6000 pieds, déplaçant ainsi d'un hélicoptère en vol stationnaire contre des cibles fixes et mobiles.

Les tests ont été développés dans des scénarios opérationnels réalistes, y compris un impact direct à 10 km, en utilisant la puissance de l'hélicoptère d'observation, mais laser désigné par une force terrestre. NIMROD Le SR est un missile lumière très précis, un guidés point laser allumé. Il a une portée de 8 km pour le lancement de la terre (10 km hélicoptère) et peut être fourni dans une variété de têtes aux missions requises. Missile léger et le lanceur ne nuisent pas à la date effective de la mission de l'hélicoptère.

Israeli mini-UAS manufacturers argue for eased export restrictions


Israeli manufacturers of micro- and mini-unmanned air systems have asked the nation's defence ministry to ease export restrictions on such equipment, claiming the current regulations are causing "big losses".
At a recent meeting companies argued that while the restrictions that apply to UAS with a larger payload potential and longer endurance make sense, those placed on the smallest systems are "not logical". Such regulations can prevent manufacturers offering designs to some potential customers entirely, or even if they are allowed, the regulations hinder the chances of winning a contract, sources say.
A defence ministry source says the problem has been presented and it will evaluate a way to ease export controls, while preventing systems from reaching "hostile hands".
In recent years terrorist organisations in [url=http://www.flightglobal.com/landingpage/Lebanon Municipal.html]Lebanon[/url] have made a number of attempts to use UAS – mostly of Iranian origin – to penetrate Israeli airspace, prompting the Israeli air force to scramble fighters to shoot them down. In recent weeks, Hamas militants in [url=http://www.flightglobal.com/landingpage/Gaza International.html]Gaza[/url] also attempted to use small commercial quadcopters.
"The terror organisations that are in a war with Israel have been trying to exploit the potential of UAS in their aggressive operations, and that forces us to be extra cautious when we approve the export of Israeli UAS of any size and weight," the defence ministry source says.

IAI on course for JSF wing deliveries

Israel Aerospace Industries (IAI) is on course to begin delivery of a contracted 811 production-standard wing-sets for the Lockheed Martin F-35 Lightning II Joint Strike Fighter (JSF) in mid-2015, IHS Jane's was told in early April.

Speaking at the company's headquarters and site of the new JSF wing production facility near Tel Aviv, Netta Kerem, Director of Marketing for IAI's Lahav military manned aircraft division said that construction of the site is proceeding to plan. The first article delivery F-35 wing assembly is expected to begin in September 2014, to be followed soon after by serial production. IAI will begin delivering the production-standard F-35 wings in mid-2015.

"IAI has invested a lot of its own money in this production facility. It should be ready in a few months, ahead of [the commencement of] deliveries of over 800 wing-sets in mid-2015," he said.

The new JSF wing production facility abuts onto the Kfir remanufacturing line, but Kerem told IHS Jane's that the processes involved in constructing the two aircraft are very different, mainly on account of the JSF's low-observable (stealth) characteristics. "It is dramatically different [how we make these different aircraft]. The stealth tolerances are so precise that the JSF line has to be fully robotic - you just couldn't do that by hand," he explained.

According to IAI, with the upper skin of the wings comprised of composite materials developed especially for the F-35 aircraft, "the automated line is characterised by the highest accuracy, including strict control of humidity and temperature conditions as well as ensuring environmental protection during the production process".

Kerem said that the new facility will be set up to produce wings for all three variants of the F-35, but that it "all depends on what Lockheed Martin want" as to what is actually manufactured. IAI's production contract is valued at USD2.5 billion and is currently set to run for approximately 15 years.

On 10 April IAI announced that Lockheed Martin CEO Marillyn Hewson had visited the new facility. A few days prior to Hewson's visit, IAI CEO Joseph Weiss told IHS Jane's that the company would be keen to expand its involvement in the F-35 programme, saying; "Of course, we are happy to do more on this plane and this is the dialogue that is going on between the two companies."

Rafael looks at Iron Dome enhancements

Armes de fabrication Israelienne - Page 16 1431042_-_main

Rafael is looking at a number of enhancements to the Iron Dome missile defence system as a result of lessons learned over recent engagements, a company official told IHS Jane's in early April.
Speaking at the company's facility near Haifa, its business development and marketing manager for the Air Superiority Systems Directorate, Gil S (the company requested that surnames of its officials not be disclosed), said several improvements are being developed, but that details and timelines are still largely classified.
"There is something in the pipeline, both in terms of hardware and software improvements [to the Iron Dome]. I can't say exactly what these are or when [they might be rolled out], but we are in a kind of race [with the Palestinian rocket firers] and we always need to update [the system] to increase the probability of a kill," he said.
Since its first successful interception on 7 April 2011, the Iron Dome has engaged more than 700 rockets with an official success rate at greater than 80% (some sources put this figure at 89%).
According to Gil S, the Iron Dome's concept of operation has changed somewhat since its first engagements, as the operators have learned to have faith in the system. "In the beginning, the IAF [Israeli Air Force] fired two missiles against every inbound target, but now the confidence of the decision-maker has changed and they no longer need to do that," he said.
Gil S noted that the Pillar of Defence campaign against militants in Gaza in November 2012 proved to be a pivotal moment in how the Iron Dome was deployed and applied. "Pillar of Defence was very important, as the co-operation between the different [batteries] was so tight - all sharing their efforts to defeat the threat."
During Pillar of Defence some 1,500 rockets were launched from the Gaza Strip towards Israel. According to figures provided at the time by the Israel Defence Forces (IDF), Iron Dome destroyed 426 rockets, with a successful interception rate of 84% (the system is designed to engage only those rockets that it determines are a threat to pre-determined centres of population, leaving the remainder to land in open country).
The IDF has released few technical details about the Iron Dome. Rafael has only confirmed that the missile's guidance system uses a 'radar seeker', and that the weapon's lethal payload is a 'special warhead'. Whatever the proposed hardware and software improvements turn out to be, it is clear that the need for Iron Dome is only set to increase in coming years.
On 12 March 2014, the Palestinian Islamic Jihad (PIJ) fired between 50 and 130 rockets into southern Israel, compared with 34 for the whole of 2013. Although these escalated strikes were ostensibly in response to an Israeli air strike the day before in which three PIJ members were killed, the PIJ and other militant Palestinian organisations will likely use such methods as a readily available and comparatively low-risk means of striking at Israel for the foreseeable future at least.

Israeli Breakthrough: Submarines Without Periscopes


A submarine without its periscope? Researchers from Israel’s Technion are developing an underwater photography and surveillance system that might make periscopes obsolete.
Close to a hundred years and always the same process: Submarine commanders who wanted to see what was happening on the surface raised their periscope with the “up scope” command, or lowered it with “down scope.”
That’s about to change. In the future submarine commanders will be able to monitor the surface from the depths without relying on periscopes. A team of Israeli researchers from the Technion’s Faculty of Electrical Engineering will present their new system at a scientific conference taking place in Santa Clara, Calfornia: A system that allows an underwater vehicle to see above the surface without a physical periscope – using a virtual periscope instead. The system is still under development, but the idea is sound and has already been successfully tested. The new virtual periscope system is called “Stella Maris,” the star of the sea.

Armes de fabrication Israelienne - Page 16 Periscope


“Divers have been using periscopes for a hundred years now,” said Prof. Yoav Schechner, along with the two doctorate students Marina Alterman and Yochai Savirski. “The periscope’s downside is the fact that it gets exposed once it rises above the water surface.” The alternative system developed by the scientists includes a fully submerged camera and a special sensor, used to create a virtual periscope and avoid exposure.
The main technical challenge was image distortion due to wave activity. In order to solve this problem the researchers founed a solution used by astronomers, a mechanism that reduces image distortion, and applied it to naval systems. This mechanism, a refracted imaging sensor, includes a thin metal sheet with precise, laser-cut holes that measure sunlight refraction, used to correct distortions in images taken by the new underwater system.
Technion researchers have already tested the system along the Haifa shores, taking pictures of team members from below the surface without using a physical periscope. Lab test results were also satisfactory. Prof. Schechner explained that “there’s still a lot to do before periscopes vanish entirely, but our work continues.”
The periscope will also have some civilian uses, such as tracking and taking pictures of birds at sea. The system, from its position on the bottom of the sea, will be able to track birds in flight, while plummeting towards the water and during their stay under the surface.

L'israélien Elbit dévoile un HUD portatif
Armes de fabrication Israelienne - Page 16 536a06855fa5f
Elbit Systems veut réinventer le HUD avec Skylens © Elbit Systems

Elbit Systems veut réinventer le collimateur tête haute, ou HUD en anglais (head-up display). L’électronicien israélien vient en effet de dévoiler le Skylens, un HUD portatif qui combine affichage de la symbologie de vol, avec un système de vision amélioré (EVS). Le dispositif se présente sous la forme de lunette relativement compacte, qui fonctionnent à la manière d'un viseur de casque pour avion de combat.

Le dispositif électronique serait compatible pour les vol de jour et de nuit, en conditions de mauvaise visibilité. Le Skylens semble avant tout destiné à l'aviation commerciale et d'affaires, et pourrait être proposé en retrofit sur des plateformes existantes.

Actuellement en cours de certification, Elbit Systems mise sur une entrée en service pour la fin de l'année 2016.

Elbit Systems est actuellement l'un des principaux fabricants de HUD et de viseurs de casque dans le monde. L'industriel israélien se partage le marché des HUD pour l'aviation commerciale et d'affaires avec les américains Rockwell Collins et Honeywell et le français Thales.

Récemment, c'est Dassault Aviation qui a sélectionné Elbit Systems pour fournir le HUD du Falcon 5X.
