VTOL AIRCRAFT.  Here are two views of René Couzinet’s original design of a circular planform, vertical take-off-and-landing aircraft.  It is claimed that

his improved version has undergone preliminary wind tunnel tests.  [CONFIDENTIAL]

specifications for the improved version are:
Span:  44.6 feet
Lifting surface area:  645.6 square feet
Six Lycoming engines (180 hp each): 1,080 hp
One turbojet (Marcel Dassault Viper): 1,639 pounds thrust
Empty weight: 9,900 pounds
Useful load:  19,800 pounds
Total weight:  27,700 pounds
According to the report, the modified version incorporates a principle of operation similar to that used in Couzinet’s original proposal, that is, two

contra-rotating discs superimposed to annul gyroscopic effect.  The discs are supported by a fixed central section in which the cockpit, the engines, and

landing gear are located.  There are now 50 adjustable vanes around the periphery of each disc instead of the 48 in the earlier proposal.
It is claimed that this improved version has already undergone preliminary wind tunnel tests, and is expected to be flown in April.  [CONFIDENTIAL]  End

Astro V Dynafan
(1964)



This VTOL made by the Astro Kinetics Corporation, is using the "Coanda effect" for vertical thrust, and could be build at much larger scale. The 3 text

images explain a lot.

An interesting quote from the text: ".. when we consider that the United States Air Force has spent seven and one-half million dollars on a circular lifting

device of different concept and abandoned the project because of inability to perfect the device." Is he talking about the AVRO projects here?
What became of this company and craft? Mysterious!

NASA's PEPP AEROSHELL
(1950s, 1966 - 1967)

The PEPP Aeroshell was created to test parachutes for the Voyager mars landing program. To simulate the thin Martian atmosphere the parachute needed to be

used at an altitude more than 160,000 feet above the earth. A balloon launched from Roswell, N.M. was used to initially lift the aeroshell. The balloon

drifted west to the missile range where the vehicle was dropped and the engines beneath the vehicle boosted it to the required altitude where the parachute

was deployed. The tests were conducted in the summer of 1966. NASA.
The voyager program was cancelled, and replaced by the much smaller Viking project several years later.
Later, NASA used the Voyager name for the Voyager 1 and 2 probes to the outer planets--these had nothing to do with the Mars program called Voyager.
There is one PEPP Aeroshell left over, at White Sands Missile Range, New Mexico.
