Autocode from Simulink to Real Time Embedded LINUx on ARM

Parabolic aircraft flights have long been productive and easily-accessed weightless test opportunities. The primary problem with parabolic flight testing is the residual acceleration environment, that is, the g-jitter from the atmosphere and engines. Any aircraft flying at these altitudes will suffer from similar magnitude g-jitter. A secondary limit is that parabola duration is limited by the vertical component of the flight velocity at the beginning of the parabola, and an aircraft design optimized for steady, level cruise with a 1.8g pull-up will be less than ideal. Proposed as a solution to these limitations is a three-flight program to develop stratospheric ultra-smooth parabolic flight capabilities of the High Altitude Shuttle System (HASS) of Near Space Corporation (NSC) and demonstrate the suitability of the stratospheric gliding parabolic flights for technology advancement and knowledge experimentation. Ultra-smooth stratospheric parabolic flight will be broadly applicable throughout spaceflight technology such as spaceflight fire safety, two-phase fluid dynamics for propellant control and life support systems, combustion in weightlessness, phase change thermal control loop operations including transients, propellant management, and slosh prediction. Successful parabolic flights in 2018 helped to advance the TRL of the technology. Parabolic aircraft flights have long been productive and easily-accessed weightless test opportunities.
