Enhancing Blue Origins Biconic capsule cross range capability with inflatable deployable delta wings and applicability to other  flight systems

    This concept might also  enable SpaceX and Boeing capsules additional cross range EDL and could be a concept that adds to the reuse and return of launch  vehicle upper  stages with or without a weight penalty trade space.Possibly allows service module/Trunk aerodynamic aerobraking and EDL.

and the inflatable winged atmosphere probe concept here,

Polidan_VAMP for STIM Meeting Jan 2013 – Final Approved

       The paper below inspired me to take this idea intended for a strategic vehicle by the authors from Georgia Institute of Technology and add in ideas by NASA Ames and the office of the chief technologist that in vision deployable EDL structures for planetary missions.The idea in my mind is two-fold; Planetary EDL vehicles with cross range on steroids! and a trade space for launch vehicle stage reuse.The launch vehicle   second stage with High re-entry speeds would serve as a test bed for both second stage reuse and planetary vehicles performing a EDL subsequent to hypersonic deceleration/aerobraking utilizing inflatable/deployable  wing systems.

Rapid Robust Design of a Deployable System for Boost-Glide Vehicles

Centaur and other upper stage derived vehicles could utilize such inflatable winged systems to EDL or navigate planetary atmospheres. An upper stage derived planetary probe could, having exhausted its fuel be pressurized to provide buoyancy. Inflatable winged systems might provide the trade space for reducing the size and volume of purely inflatable systems such as balloon probes.

The upper stage could have brought with it its own payload which would be an orbiter.

Launch vehicle stages intended for reuse imply holding back fuel for the propulsive descent and it this that has a payload penalty, like wise an inflatable system be it a winged  or a ballut also would have a weight penalty.A inflatable winged system would allow trades  with a return from down range to a suitable infrastructure that enhanced cross range would allow.

Sub orbital inflatable winged systems testing would inform the state of the art to planetary probe EDL systems as well as human crewed ones. Sub orbital  or orbital second stage inflatable systems would further inform us.

Inflatable winged systems could inform us as to the feasibility of aerobraking into LEO from L1, L2 and High lunar Orbit. This implies a EDL subsequent to aerobraking.Such high energy aerobraking from cis lunar space followed by EDL might make sense with scarce ISRU fuel to LEO combined with a smaller EDL winged vehicle.Utilizing cis lunar deployable winged vehicle test vehicles better informs us as to planetary systems aerobraking with a subsequent EDL.

     repurposing spent stages as EDL and planetary probes is a more daring planetary probe trade space! The fuel tanks would be pressurized for buoyancy with a source of thrust to keep the flight system aloft in planetary atmospheres.

Many astrodynamic trajectory scenarios with sub optimal trajectories might be enabled by EDL followed by inflatable winged systems to correct for or enhance mission design.
