TECHNICAL: DEFENCE tUl._.'i J r 1 -«i.- ' <* MM H Testing in the spray: the V-22 lands on VSS Wasp... V-22 survives marine test The Bell-Boeing V-22 Osprey tilt-rotor has completed ini tial shipboard compatibility tests aboard the amphibious as sault ship, USS Wasp. Two V-22s, aircraft Nos 3 and 4, were used in the tests after being ferried from the Naval Air Test Center at NAS Patuxent River, Maryland. The aircraft ...as part of the second developmental were configured for the Marine Corps combat-assault mission and were equipped with an up dated automatic flight-control system. The tests, conducted between 4 and 7 December, were the primary event in the V-22's second developmental-test pe riod. • test period Dowty awarded actuator contracts Two contracts, together worth more than £3.25 mil lion, for the leading-edge slat actuation system and slat-lock actuators for the McDonnell Douglas T-45 Goshawk, have been awarded to Dowty Aero space Wolverhampton in the United Kingdom. The actuation system com prises a pair of mechanically synchronized units, each with its own separate lock jack. Dowty Aerospace Wolver hampton has also won all three contracts for the Hawk nose- wheel steering system, with the total current value of the com petitively tendered contracts in excess of £1.7 million. The contracts are for the hy draulic control, the electronic control and the integration of the complete system. Dowty Aerospace Peterborough of Can ada will supply the equipment units, analytical test equipment and system knowledge for the integration of the system com ponents at Wolverhampton. • High costs cause NLOS cancellation The US Army is to cancel development of the Boeing/ Hughes non-line-of-sight mis sile (NLOS), citing an unaccept able rise in the cost of the full-scale development (FSD) programme due to deliberate underbidding by contractors. The Army says that the Boe ing/Hughes team, and its com petitors, Martin Marietta and Raytheon, both made "unrealis- tically low" proposals for the $131 million FSD contract, which was awarded in Decem ber 1988. Despite an attempt to restructure the programme ear lier this year (Flight Interna tional, 18-24 April), the Army now estimates the total FSD cost at about $400 million. The Army had originally in tended to buy 16,000 NLOS missiles, based on its original fibre optic-guided missile con cept. Boeing and Hughes claim that costs grew because the Army added items such as field and classroom trainers to the FSD programme requirements. The Army dismissed these claims saying: "This award was well below the Government es timate of the cost to complete the full-scale development of the NLOS system." • GEN-X decoy production date close Texas Instruments (TI) has completed development of the GEN-X radio frequency ex pendable decoy, set to enter service with the US Navy. The electronics for the decoy, which is ejected from the parent aircraft to emit radar-like sig nals to lure missiles away, are housed in a cartridge 140mm long and 35mm in diameter. Following on from the POET system, GEN-X has a wider frequency range. When ejected, the battery driving the jamming signal is activated and tail fins are deployed. Tl was awarded the $ 117 million contract to develop and produce GEN-X in August 1987. Full-scale-development deliv eries have recently been com pleted and the production phase is expected to begin towards the middle of this year. • The GEN-X decoy emits a jamming signal to protect the parent aircraft FLIGHT INTERNATIONAL 2 - 8 January, 1991 17
