Telescopic Sighting System
The Telescopic Sighting System (TESS) was a sight used on the FV4201 Chieftain tank and RAF F-4 Phantom aircraft. Usage The TESS was trialed and introduced in the early 1980s originally as a tank sight for the FV4201 Chieftain. Surplus stocks were used on F-4 Phantom aircraft operated by the Royal Air Force as a cost-saving measure for a long range daytime target identification device, whereas the United States Air Force used the TISEO on their F-4 Phantoms. The TESS was installed in the rear cockpit in the centre window section for the Radar Intercept Officer to use. It was boresighted to the aircraft weapons system and when locked on target, the target was magnified six times.

XV426 (32195090654)
The Lockheed XV-4 Hummingbird (originally designated VZ-10) was a United States Army, U.S. Army project to demonstrate the feasibility of using VTOL for a surveillance aircraft carrying target-acquisition and sensory equipment.Hummingbird A Promising Augmented-Jet VTOL Aircraft ''Flight International'', 3 April 1962 It was designed and built by the Lockheed Corporation in the 1960s, one of many attempts to produce a V/STOL vertical take off/landing jet. Both prototype aircraft were destroyed in accidents. Design and development Vertical take-off lift was obtained by exhausting the engine flow downward through multiple nozzles, augmented by a secondary flow of cold air. But the performance was far below estimates with only a 1.04 ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
