Research Progress of Dynamic Thermal Sealing Technology For Hypersonic Vehicle
摘要
Abstract
Aerodynamic heating caused by high Mach number flight has always been the major factor that restricts the development of aircrafts to higher speed ranges and airspaces.In particular,parts with large dynamic clearance between the engine nozzle and fuselage,and the control rudder of the tail wing,pose a technical challenge for dynamic thermal sealing more difficult than fuselage surface heat protection.Hence,dynamic thermal sealing technology is a critical bottleneck for developing new hypersonic space vehicles.This paper surveys the foreign dynamic thermal sealing technology with examples of X-38 and other aircrafts,reviews its main technical categories and key performance test methods,and finally offers a summary and future outlook on the development of dynamic thermal sealing technology.关键词
