The Intermediate eXperimental Vehicle (IXV) is an European Space Agency (ESA) experimental re-entry vehicle intended to validate European reusable launchers that could be evaluated in the frame of the Future Launchers Preparatory Programme (FLPP).[7] The IXV development would be carried out under the leadership of the NGL Prime SpA company.[6] It would inherit the principles of previous studies such as CNES's Pre-X and ESA's AREV (Atmospheric Reentry Experimental Vehicle).

Design

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.[8]

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.[5][9] Initially scheduled to make its first orbiting flight in 2013,[10] the next plans were to launch the IXV on 18 November 2014[11] by a Vega rocket,[12] the ESA’s new small launcher, descending to the Pacific Ocean for later recovery and analysis of the recorded mission data.[13] The total estimated cost for the project is 150 million euros.[4]

Performance

Pre-launch testing

The IXV's subsonic parachute system was tested at the Yuma Proving Ground in Arizona in late 2012.[14] Water impact tests were conducted at Consiglio Nazionale delle Ricerche's INSEAN research tank near Rome.[15]

On June 21, 2013 an IXV test vehicle was dropped from an altitude of 3 kilometres (1.9 mi) in the Salto di Quirra range off Sardinia. The test was to validate the water landing system including the subsonic parachute, floatation balloons, and beacon deployment. A small anomaly was encountered when inflating the balloons, but the other systems performed as expected. After the test the vehicle was taken for further analysis.[16]

On June 23, 2014 the recovery ship Nos Aries conducted a training exercise with an IXV test article off the coast of Tuscany.[17]

In June 2014 the IXV test vehicle arrived at the ESTEC Technical Centre in Noordwijk, the Netherlands, to undergo a rigorous test campaign to confirm its flight readiness in anticipation of a flight on a Vega rocket in November.[18]
