On February 7, 1952 the A.V. Roe Special Projects Group distributed an internal document titled ‘Description and Thoughts on the Turbo Disc’ (a simple gas turbine halfway between a ram-jet engine and centrifugal engine), Frost also submitted the design to the engineering department of McGill University.Looks nice, but I don't think it can fly
- On March 27, 1957 USAF extended the Project 1794 through October 1958 under the codename Weapons System WS-606A.I hope this document reference appears in your upcoming book. Weapons System 606A was the designation for the failed Avrocar. It was also the designation for the above aircraft but with the words (Supersonic Application).
Posted hereRene Couzinet developed a similar aircraft and photos of a scale model were published. Patents were filed in France in May, 1955.
The Ljungstrom Brothers' first few steam turbines had radial out-flow discs and generated shore power for many decades. But the Ljungstrom Brothers soon switched to more efficient axial-flow turbines. I doubt if anyone has built an efficient radial out-flow turbine during the last 100 years." ... There is no evidence that anyone has engineered an example of radial-flow turbo-disc engine."
