Israel Aircraft Industries Lavi


The Lavi, a single-engined canard delta with a chin intake, is similar in appearance to the F-16 but is smaller. A 91.7kN Pratt & Whitney PW1120 turbojet is used, and the aircraft has a quadruplex digital fly-by-wire control system which allows relaxed stability. The cockpit is built around three multifunction colour CRT displays and a wide-angle headup display. The new Elta multimode pulse-Doppler radar, developed from the earlier EL/M-2021B, will include track-while-scan capability in air-to-air mode, and terrain avoidance/ground mapping in air-to-surface mode. Composite materials are used extensively in the airframe, and account for 22 per cent of the structure by weight. Grumman designed and developed the wings, and will also build the first eight sets before production transfers to Israel.

A second prototype flew on March 30, 1987. The first prototype, which flew on December 31, 1986, and the second aircraft are both two-seaters, while the remaining four development aircraft were to be single-seaters.

The program was ultimately cancelled, the constructed prototypes went on to see a serviceable life as technology demonstrators for various other flight programs to test avionics and applicable flight systems. It is believed that Israeli involvement in the Chinese program culminated in a similar-looking airframe with multirole capability in the J-10.
