内容記述 | The thrust performance of airframe-integrated linear aerospike propulsion systems for high-speed aircraft operated under off-design in-flight conditions was evaluated, based on performance prediction models established for linear aerospike nozzles by accounting for the freestream effect. The airframe configuration, equipped with a boattail appearing to the right upstreamof the primary cell nozzle exit, enabled the freestreameffect to be used for increasing the spike surface pressure. Performances of each thrust component were predicted by using the physics-based models established in separately performed studies. First, a parametric studywas conducted on a rocket primary thruster with various design parameters. Then, an advanced concept with an airbreathing primary propulsion systemwas evaluated for its feasibility by comparing its thrust performancewith that of a conventional rocketprimary thruster.The benefit of the aerospike nozzle integrated into the airframe was also evaluated by comparing its thrust to a configuration without the aerospike nozzle. Results showed that the employment of the aerospike nozzle offered improved performance from takeoff to cruise phases. The advanced concept using the bypass airbreathing system for the primary thruster followed by the aerospike configuration exhibited further improvement in thrust by compensating for the boattail drag. | |||||
