Abstract
The accurate landing of entry capsules on other planets and moons depends on accurate
knowledge of the aerodynamic behavior of the landing vehicle. The problem is that at
the hypersonic speeds that are experienced by entry capsules during atmospheric entry,
it is very hard to predict the capsule's behavior.
This project, The Measurement of Entry Capsule Aerodynamic Force Coefficient aims
to improve the original aerodynamic force measurement system that is used in the
University of Southern Queensland Gun Tunnel.
After an analysis of the previous method of force measurement and a review of other
force measurement systems a new system was designed for the Gun Tunnel. This will
allow for the prediction of normal and axial forces on an entry capsule model, as well
as the location of the centre of pressure.
The first test run of this project aimed to identify the aerodynamic forces acting on
the Japanese, MUSES-C Entry Capsule during a Mach 7 flow in the USQ Gun Tunnel.
During this test only the axial force was measured. This force was then compared to a
prediction based on a Newtonian Flow model.
