氢电混合动力公务机BYA-1风洞测试取得成功

Core Viewpoint - Beyond Aero has successfully completed the first wind tunnel test of its BYA-1 aircraft, validating the planned aerodynamic performance of the aircraft [2] Group 1: Company Overview - Beyond Aero is a French aerospace startup focused on developing hydrogen-electric hybrid propulsion systems [2] - The company aims to finalize the design of the BYA-1 aircraft, which has a range of 800 nautical miles (1480 kilometers), by around 2027 and plans to enter service in the early 2030s [2] Group 2: Testing and Performance - The wind tunnel tests were conducted at the low-speed wind tunnel facility of the Dutch company Marknesse, using a 1/8 scale model of the BYA-1, with test speeds reaching up to 155 knots (288 kilometers per hour) [2] - The tests particularly focused on the layout of gaseous hydrogen tanks at the wingtip and wing-body junction, which creates "complex aerodynamic interaction areas" where even minor geometric changes can significantly affect lift, drag, and stability [2] - In addition to performance optimization, the series of tests aimed to demonstrate that the configuration performs stably, predictably, and controllably within the expected flight envelope [2]
