The ALR Piranha was a project in the late 1970s involving a lightweight multi-role combat aircraft with canard wings. It was a project of the Swiss Working Group for Aerospace (ALR), which is the maintenance and entertainment unit of the Swiss Air Force. The manager of the project was Georges Bridel, an engineer of ETH Zurich.〔Küng,Paul. Piranha, Eine neue Generation leichter Überschall-Kampfflugzeuge? Flug-Revue, January 1979, S. 27 - 29〕 ==History== After the Swiss government had cancelled the FFA N-20 and the order of 100 FFA P-16s, the Swiss aviation industry and the ETH Zurich made a last attempt for their own Swiss fighter aircraft. It should be a small fighter plane similar in class to the F-5E which the Swiss Air Force later ordered. Studies conducted in the 1960s and 1970s required modern aircraft equipment that was too expensive for small states to afford. The increase in the cost of flight material and weapons shrank the fleet sizes and their performance in combat. The projected design would also require common parts that could be built to support different missions - the aircraft would be used for air and ground attack, reconnaissance, electronic warfare, and operational training.〔Paul Küng: ''Flug Revue'', January 1979, S. 27〕 This presented a small fighter plane, with respect to the F-5E, with significantly reduced size (20% smaller surface).〔Paul Küng: ''Flug Revue'', January 1979, S. 29〕 The Piranha design was of close-coupled canard arrangement, with a shoulder-mounted, low aspect ratio main wing of near-delta plan.〔''Air International'' February 1980, pp. 78–79.〕 Seven hard-points for weapons were planned, with four under-wing pylons and one on the aircraft center line rated at and rails on the aircraft's wingtips for air-to-air missiles such as the AIM-9 Sidewinder or the R.550 Magic. A single cannon, either the heavy, powerful 30 mm Oerlikon KCA or the lighter Mauser BK-27, would be mounted on the aircraft's center line, with the nose wheel slightly offset as a result. The ALR would have been equipped with avionics, radar, armament and engines from abroad. In front of the cockpit would be placed a Laser seeker sensor.〔http://www.sharkit.com/sharkit/piranha/piranha_notice.jpg see Nr3〕 Air brakes are applied to the sides of the rear hull in the single engine version. In the twin-engine version of the two air brake flaps are placed on the upper fuselage near the vertical tail. The ALR would be in a single engine version, powered by RB199, EJ200 or M88 or offered in a twin-engine version (with two Larzac). Only the rear part of the twin engine to the single engined version would be different in the size, the arrangement of the parachute container, and the air brakes. The Swiss government was not interested in the project. There was wind tunnel testing and flight testing in Emmen with remote-controlled model airplanes. Also, a real-size mock cockpit was created. A new concept for aircraft bunker with a rotating floordisc in the bottom for a simple handling of the aircraft in the aircraft bunker was designed. But no prototype nor aircraft bunker was built. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ALR Piranha」の詳細全文を読む スポンサード リンク
