Great find my dear Harrier,harrier said:Cranfield report covering many projects 1979-1996:
https://www.youtube.com/watch?feature=player_embedded&v=xUipGlWHWFcA few weeks before the opening of the Paris Air Show, we introduce you to the V10 SparrowHawk, a plane designed by Cranfield University with the help of engineers from MSC Aerospace Vehicle Design.
[first image attached below]
The SparrowHawk combines the advantages of an helicopter, vertical takeoff and top speed of 222kph, with aircraft features: 31.000 feet ceiling, 620kph top speed and loading capacity of 2.5 tons.
For this project the objectives were maximum efficiency and space optimization, therefore the tanks are placed in the wings with a specially designed structure.
Three architectures are envisioned, based on a RTM322 01/9A Rolls Royce engine

Because of the aircraft requirements and given the actual technologies an electric propulsion couldn’t be fitted now, nonetheless two alternative solution were studied, fuel cell and turboelectric.
From the two the Turboelectric was the most adapted solution, in this configuration the energy generated by the Rolls Royce RTM322 Turboshaft is sent to generators which convert it into electricity, the electrical system (cables, controllers and motors) is cooled through liquid hydrogen.
Cranfield University video of the Rawfeed rolling assisted wire-and-arc additive manufacturing process for producing titanium critical structural components for aerospace applications. Wire-fed welding torch lays down a bead of titanium, which is then cold-rolled to refine the grain structure and improve the mechanical propertes of the material. Airbus Group leads the Rawfeed project with Cranfield, Delcom and the University of Bath.
anther two projects to Cranfield,a VTOL freighter and 3 mach SST aircraft.
