Estimation of Aero- and Aerothermo-Dynamic Characteristics for HTV-R

Abstract

A series of aerodynamic tests have been conducted for the preliminary design of large scale recovery capsule HTV-R . Wind tunnel tests from low to hypersonic speeds and numerical analysis were conducted to establish the HRV aerodynamic database for the HTV-R’s design. Experiments to improve testing and estimation capability of transonic dynamic stability characteristics, parachute characteristics at low speeds, and hypersonic RCS jet interaction were conducted for the development of the HTV-R program. This paper provides a summary of the objectives and scope of the aerodynamic tests.
