    Abstract

    This report describes the progress of work done in the project "Experimental study on conical aerospike nozzles" to be carried out in the 0.5m base flow facility at NAL. The main objective of the project is to gain a broad understanding of the aerospike flow physics that is responsible for its altitude compensating characteristics. Measurements include wall pressures on the spike surface and base pressure (for truncated spike configuration) with and without free-stream Mach number effect. The various model components, such as the jet pipe extension, two afterbodies (cowl-length variation), one 100% length spike and one 40% length spike have been fabricated. Fabrication of pressure taps on the spike surface is presently going on. Four Kulites (XCE-062) for wall pressure measurements have also been procured.
