The Intermediate eXperimental Vehicle (IXV) is a European Space Agency (ESA) experimental re-entry vehicle intended to validate European reusable launchers which could be evaluated in the frame of the FLPP program. The IXV development would be carried out under the leadership of the NGL Prime SpA company. It would inherit of the principles of previous studies such as CNES' Pre-X and ESA's AREV (Atmospheric Reentry Experimental Vehicle).
IXV uses a lifting body arrangement with no wings of any sort, using two movable flaps for re-entry flight control. Re-entry is accomplished in a nose-high attitude like the Space Shuttle, with maneuvering accomplished by rolling out-of-plane and then lifting in that direction, like an aircraft. Landing is accomplished by parachutes ejected through the top of the vehicle. The airframe is based on a traditional hot-structure/cold-structure arrangement, and is supported on-orbit by a separate maneuvering and support module similar to the Resource Module intended for the Hermes. The avionics are controlled by a LEON2-FT microprocessor, and interconnected by a MIL-STD-1553B serial bus.
On December 18, 2009, ESA announced a contract with Thales Alenia Space valued at 39.4 million euros to cover 18 months of preliminary IXV work. Initially scheduled to make its first orbiting flight in 2013, the current plans are to launch the IXV during 2014 by a Vega rocket, the ESA’s new small launcher, descending to the Pacific Ocean for later recovery and analysis of the recorded mission data. The total estimated cost for the project is 150 million euros.
