Stabilized detonation for hypersonic propulsion [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance There is now an intensifying international effort to develop robust propulsion systems for hypersonic and supersonic flight. Such a system would allow flight through our atmosphere at very high speeds and allow efficient entry and exit from planetary atmospheres.

Some Key Issues in Hypersonic Propulsion [PDF]
Energies, 2021 This paper summarizes and discusses some critical aspects of flying hypersonically. The first is the L/D (lift over drag) ratio determining thrust and that in turn depends on the slenderness Küchemann’s τ parameter.

Hypersonic propulsion. Past and present [PDF]
, 1990 The change of the concept of hypersonic speed with time is in the first place briefly discussed. The evolution of the hypersonic propulsion is restricted to the history of the ramjets. Considering the abundance of excellent literature on the subject only the most remarkable achievements are commented.
