HyperPASS-Hypersonic Planetary Aeroassist Simulation System
HyperPASS
Intro
HyperPASS is an aeroassist simulation software
package coded using the MATLAB language. It enables
users to perform simulations at various planets
using pre-programmed vehicles or user-entered vehicles.
It allows users to perform trade study simulations
without prior knowledge of MATLAB, by way of graphical
user interfaces (GUIs).
HyperPASS
Uses
Mission studies of aerocapture systems at
planets with atmospheres.
Trade studies to investigate performance
with alternate aeroshell types, varying flight
path angle and entry velocity, different g-load
limits, angle of attack and angle of bank variations.
Educational purposes because of its ease of use.
HyperPASS
Capabilities
Simulations at Venus, Earth, Mars, Jupiter, Saturn, Titan, Uranus, and Neptune
During the mission
setup function, the planet, atmosphere, gravity
model, and vehicle are chosen. Atmosphere models
are pre-programmed exponentially interpolated
tables or the user may enter their own table.
Gravity models include inverse-square rotating,
J2 rotating, and inverse-square non-rotating.
Vehicles include Apollo, Viking, Elliptical Raked-Cone
(AFE), or user-entered vehicles.
Simulations can be automated in
order to carry out trade studies on the variations
of key aerocapture parameters. Afterwards, output
can be viewed and plotted for further analysis.
Below is a sample state-vector output plot from
a HyperPASS guided aerocapture simulation at Mars.
