French R&T effort for hypersonic airbreathing propulsion is focusing on needed technologies for the propulsion system and acquisition of aero-propulsive balance prediction capability. A large part of technology development effort can be led on ground and is currently dedicated to combustion chamber to ensure its performance and thermomechanical strength. On the contrary, it is mandatory to flight demonstrate capability to predict the aero-propulsive balance. In that view, MBDA and ONERA are leading the flight testing LEA program. Started in January 2003, the program will end in 2015 after 4 autonomous flight tests of an experimental vehicle in Mach number range 4 to 8. Guidelines for LEA vehicle and its propulsion system design have been validated in 2006 by a Preliminary Design Review. The running Phase 2 aims at getting a detailed design while validating the aero-propulsive configuration by a first free jet test series to be performed early in 2011.

Since 1993, MBDA-F and ONERA have been working with many Russian laboratories and institutes in the topic dealing with future high speed airbreathing propulsion system. Particularly, the fruitful cooperation between Moscow Aviation Institute and MBDA France goes on to prepare together a Wide Range Ramjet able to accelerate a reusable space launcher from at least Mach 3 and up to Mach 12. This work has been realized with several cooperative contracts, funded by French Government and by MBDA-France. MBDA-France and the Moscow Aviation Institute are developing an experimental wide range dual-fuel, dual-mode ramjet. The considered engine has a fully variable internal geometry which gives it a priori a high performance level over the whole Mach number range. Technology development work led to the design and partial demonstration of materials and structures solutions to comply with the variable geometry requirements. Combustion tests and other basic research have taken place for more than 7 years at Moscow Aviation Institute. These technologies should be definitively demonstrated thanks to the test of a large scale Prototype in MBDAFrance Bourges-Subdray Center (connected pipe test up to Mach 7 -entrance of combustor 212x257 mm ² ). Specific computer codes are achieved, allowing to control the Prototype and in particular to optimize its contour in real-time during the test. Numerous subscale tests have been realized (with fixed or simply moving internal geometry) in order to better understand the combustion in the regimes that would occur in a dual-fuel dual-mode ramjet. This cooperation gives also the opportunity to work together on the development of new measurement systems and of a methodology associated with hot fuel-cooled structures for WRR. This paper gives a synthesis and an overview of this common work, with consideration to all aspects.

“…Some specific works have been performed to adapt computation codes to this particular fuel (Ref [51] and [52]). By another way, ONERA LAERTE and ADT5 test facilities have been upgraded to make possible basic experiments to better understand mixing and combustion process of CH4/H2 (LAERTE) and perform direct connected pipe combustion test for LEA combustion chamber (ATD5).…”
