Abstract
ABSTRACT: Hypersonic propulsion systems, such as supersonic combustion ramjets (scramjets) are generally expected to operate from Mach 3.5 up to Mach 7-8 and are designed for specific flight Mach numbers to achieve optimum performance. However, realistic flight vehicles will experience a wide range of flight conditions during a typical mission. These off-design flight conditions degrade the performance of the hypersonic propulsion system because the engine is not actively controlled. In an effort to increase engine performance, while simultaneously enabling system weight reductions, PM & AM Research, in collaboration with University of Arizona and Texas A & M University, propose to demonstrate the feasibility of depositing energy using"plasma"actuators within a hypersonic propulsion system. BENEFIT: If successful, this solution would allow increased thrust and robustness. Military applications for this innovative system include high-speed propulsion systems and technologies applicable toward various time-critical weapon systems, strike/reconnaissance vehicles, and space launch applications. Additionally, commercial applications include enhancing current scramjet system designs to enable access to space applications to compete with existing rocket platforms.
