Research Interests


Scramjets and Hypersonic Technologies

A scramjet (supersonic combustion ramjet) is a variation of a ramjet with the distinction being that the combustion process takes place supersonically. At higher speeds, it is necessary to combust supersonically to maximize the efficiency of the combustion process and to avoid the losses induced by a final normal shock.

Like a ramjet, a scramjet essentially consists of a compression ramp inlet where air is compressed by the high speed of the vehicle, a combustion chamber where fuel (mainly hydrogen) is combusted, and a nozzle through which the exhaust jet leaves at higher speed than the inlet air. Also like a ramjet, there are few or no moving parts, making the scramjet geometrically quite simple. However, a scramjet works only at high flight speeds (above Mach 7) and thus will always be only one part of a combination engine.

Hypersonic technology is closely linked to scramjet technology because scramjets operate at hypersonic speed. In aerodynamics, hypersonic speeds refer to highly supersonic flow, somewhere above Mach 5. There is no distinct borderline between the supersonic and hypersonic regime, like there is between subsonic and supersonic flow. Rather the term hypersonic refers to certain physical effects becoming important like

  • High temperature effects (molecular dissociation and ionization)
  • Entropy layers
  • Viscous interaction
  • Thin shock layers
All of those play an important role when designing a system for hypersonic speed.

Within the frame of the Research Training Group (GRK 1095/2) „Aerothermodynamic Design of a Scramjet Engine for Future Space Transportation Systems“ we are working on designing a scramjet demonstrator for flight testing and at the same time developing new simulation tools for hypersonic flow.
