Aerospike Rocket Motor Structural Webbing
… of technologies relating to the annular aerospike nozzle. In order to prevent undesirable deflection of the cantilevered spike, a structural stiffening web, referred to as “The Spider,” is proposed. The Spider resembles a three-spoked wheel, with the aerospike held by the inner hub and …

Aerospike Thrust Vectoring Slot-Type Compound Nozzle
A study of thrust vectoring techniques of annular aerospike nozzles was conducted. Cold-flow blow-down testing along with solid modeling and rapid prototyping technology were used to investigate the effects of slot size, placement, geometry and orientation. The use of slot-type compound nozzles …

Hole-Type Aerospike Compound Nozzle Thrust Vectoring
Compound aerospike nozzles were designed and tested as part of an ongoing experimental study to determine the feasibility of thrust vectoring an aerospike nozzle with the addition of a secondary port. Earlier phases of the study have indicated that a compound aerospike nozzle could provide …

Wake closure conditions in plug nozzle flowfields
The aerospike, of plug, nozzle is being proposed for future space launch vehicle applications. The design of the nozzle involves complex wake structures that directly affect engine performance. In particular, the closed or open wake condition of the flow determines the dependence of the base …

Improving the Performance of Re-entry Vehicle in Hypersonic Flow by Morphing Nose cone by Bio-Mimicking Honey Bee Abdomen
… nosecone morphing honey bee abdomen with flat D-aerospike. The presence of a strong bow shock in honey bee abdomen morphed nosecone without spike generates significant drag, which diminishes in its alternate position. During the honey bee 's extension, both at 2.5 degrees and 5 degrees, the drag …
