UPSTREAM STUDIES
Developments for the Rafale
TWO PEA INTENDED TO IMPROVE THE PERFORMANCE OF FRENCH AIR COMBAT IN DETECTION AND ELECTRONIC WARFARE.
The need for export support overcomes the cult of confidentiality that usually accompanies the evolution of programmed Rafâle.An Paris Air Show, the Directorate General of Armaments and presented at its stand two upstream study program (PEA ). currently funded. to improve the performance of the French fighter in the detection and electronic warfare.
INCAS
It was, for the first time presented to the public a PEA called Incas (Integration of new capabilities to Spectra), which has two sub-parts. One, we have already presented several
, rçprises "in" An & Cosmos "■ focuses on the development of a new antenna operating Spectra gallium nitride (GaN).
Unpublished, the LEA (active electromagnetic Lure) project was, however, presented for the first time at the Paris Air This involves the development of a deployable asset lure that would confuse the seeker of some air missiles -air in their terminal phase guidage.At least four decoys could be carried away by a rafale in the same location as the current chaff at the rear of the fuselage. Contrary to that team for example "Eurofighter, this lure would be towed by the plane, but dropped: he would not have either of propellant.
"Such a system would effectively complete the Spectra system, already integrated in the aircraft, to thwart some very specific threats such as homing air-to-air missiles operating in the Ka band," says, in the lounge, an engineer of armament .
The DGA had also for the first time, called PEA Tragédac. Notified in 2010, it aims to equip the Rafale with a capacity of passive target localization thanks to a set of device network had the same patrol. Specifically, two Rafale detecting a target
through either their frontal sector optronics (OSF) or Spectra could improve the positional accuracy of their aim or exchanging data via the link 16 A change purely logicicllc but, according to DGA. would be especially complex to implement the point of view of the data synchronization between the devices.The first test flights should start by year-end to collect data
CARAA
Even if they were not presented at Le Bourget, others are now turning PEA consulting firms Dassault and program partners. This is the case of PEA Caraa (additional capabilities for radar â active antenna), awarded to Thales in late 2011 and aims to put the develop a material modification to the radar to make it more efficient to face evolving threats has low speed and low altitude, but also to make it capable of detecting ground targets.
From a technical perspective, the idea is to divide the large antenna subsets, each consisting of a few hundred transceiver modules each of these subsets then enjoying a digitizing the signal that would be her own. So that today, all Elements, radiant are ultimately combined into one lane.Thales should test flight, the 2014-2015 horizon. Such an amendment to aidc of one of its prototypes RBE2-AESA.
DEDIRA
Top Secret, PEA Dédira (demonstrator Rafale discretion) does. however, been no communication the living room, and has also never been formally addressed. This work, aimed at improving stealth Rafale, however, subject of a major fundraising effort for several years, corroborating sources, raw changes should be tested shortly size, are they? Mystery ...
