ABSTRACT:
Successful flight of high altitude military aircraft is dependent, in part, pon the ability of the aircraft to remain undetected during flight. Against the highly sophisticated infrared sensors developed during recent years, particularly for miliary use, an aircraft powered by a gas turbine engine is at a particular disadvantage. Hence infrared emissions from gas turbine engines have been reduced by use of a variety of infrared radiation (IR) suppressor designs. But in these designs aerodynamic problems are difficult to analyze and geometrical parameters are very critical, and nearly impossible to maintain. The IR suppressor herein provides the best blend of simple aerodynamics, heat transfer, and geometry.
