Abstract
The development of accurate simulators depends on experimental data and high-fidelity simulators used as a benchmark. The methodology for the development of new simulators consists of successive refinements starting with low-order models. Low-order models allow the overall parameters evaluation of a project in its early stages. This article introduces a low-order simulator called Low-order Hypersonic Vehicle Trajectory Simulator (LHVTS). Its validation consists of comparing the results with the program ROSI, a computational tool validated for decades with experimental flight data. LHVTS is applied in a case study of a hypothetical hypersonic vehicle that must be accelerated by a Brazilian VSB-30 rocket until reaching Mach 6.8 on atmospheric re-entry at a geometry altitude of 30 km. It is concluded that the hypothetical hypersonic vehicle and its service module must weigh less than 400 kg to achieve these flight conditions. Results like this illustrate the usefulness of low-order models in evaluating overall design parameters to determine some of the key requirements of a hypersonic vehicle.
