Abstract
LAPCAT II has passed its first out of three consecutive periods allowing to report the first technology achievements. The main steps are related to the two vehicle conceptual design. The Mach 5 LAPCAT A2 has been further detailed in its multi-disciplinary layout whereas the Mach 8 design has been worked out along four different concepts. Detailed analyses of these different concepts are performed on the basis of CFD or Nose-to-Tail computations. Experimental campaigns and specific technology developments related to the conceptual designs have now been initialized and are mainly driven by the vehicle requirements and constraints. This covers aerothermodynamical phenomena specific to intakes and completely integrated aero-propulsive models exploited to improve the development of e.g. Nose-to-Tail simulations. Combustion experiments & modelling for both subsonic and supersonic combustion are being prepared to assess both the performance of high-speed engine cycles as well their environmental impact in terms of NOx and Ozone depletion.
