Entry, Descent, and Landing with Propulsive Deceleration: Supersonic Retropropulsion Wind Tunnel Testing

  title={Entry, Descent, and Landing with Propulsive Deceleration: Supersonic Retropropulsion Wind Tunnel Testing},
  author={Bryan A. Palaszewski},
The future exploration of the Solar System will require innovations in transportation and the use of entry, descent, and landing (EDL) systems at many planetary landing sites. The cost of space missions has always been prohibitive, and using the natural planetary and planet s moons atmosphere for entry, descent, and landing can reduce the cost, mass, and complexity of these missions. This paper will describe some of the EDL ideas for planetary entry and survey the overall technologies for EDL… 
Launch Vehicle Recovery and Reuse
The economics of reuse is presented as a basis for recommendations for cost effective reuse and recovery of booster components and non-propulsive approaches as economic alternatives to propulsive approaches are considered.
Flow Field Characterization and Visualization of Grid Fin Subsonic Flow
Grid fins are unconventional control surfaces consisting of an outer frame supporting an inner grid of intersecting planar surfaces. Although afflicted with higher drag, these have been credited for
Effect of aspect ratio variation on subsonic aerodynamics of cascade type grid fin at different gap-to-chord ratios
ABSTRACT This paper dwells upon investigating the effect of aspect ratio (AR) variation on the aerodynamic performance of unconventional control surfaces called grid fins by virtue of a series of
