Abstract:

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. Less divulged historical events, such as the propulsion of helicopters by ramjets are discussed with more detail, and special attention is given to the contributions of Spain to supersonic combustion. The present state of the hypersonic propulsion is commented, reviewing from the literature on the subject some of the most demanding problems facing the propulsion systems of the Aerospace Plane and of the Hypersonic Cruise Aircraft.
