About VEXREDUS

A closer look on the experiment.



VEXREDUS is an acronym for "Vehicle with EXtended REentry Duration - University Stuttgart". It is a student experiment for the REXUS/BEXUS-Campaign.


Scientific and technical background

The scientific and technical background is the search for new reentry methods, with the goal to make this very critical phase of every returning space mission less dangerous and therefore more convenient. One Way of solving this problem might lie in the construction of reentry vehicles with a high L/D-Ratio, making a separation and overall reduction of mechanical and thermal loads possible.


Experiment Objectives

The mission objectives are:
  • To get insight on the aerodynamic behavior in low density atmospheric layers of an unconventional shaped blended wing body glider concept
  • To autonomously return to a predefined landing site
  • To record High Definition Video by an onboard camera

Optional mission objectives might be the gathering of data from additional sensors like atomic oxygen sensors, microphones, etc.


Experiment Overview

The experiment consists of a glider that shall partly test reentry behaviors of an unconventional shaped blended wing body concept. The glider will be placed beneath the balloon, dropped at reaching a desired height and will then autonomously glide back to the landing site. This is achieved by an onboard autopilot system that will be capable of waypoint navigation. Insight on the aerodynamic behavior will be gained by combining all the onboard logged data of the autopilot system, like position, speed, attitude, pressure, temperature, g-loads/accelerations with the onboard captured high definition video.
