AMR Helicopters and Projects

[hesham]

Hi,


I spoke before about the AMR (Aero-Marine Research) XD-110,as it was RPV;
http://www.secretprojects.co.uk/forum/index.php/topic,1303.msg10858.html#msg10858


But the company developed some manned helicopter and one STOL aircraft,the XR-200
was two-seat autogyro,had a two-blade rigid main rotor and a 75 hp light engine
driving a rear-mounted Benson External Rotorduct,it was actually built,also the XR-207
Rotorplane was five-seat compound helicopter project,powered by two Continental
engines.


The XD-110C was a double-delta business jet STOL aircraft project,it accommodated
2 crew and 8 passenger.

Benson / AMR also worked with Ryan to build a demonstrator for the Ryan mini-RPV:

AMR (Aero-Marine Research) RPV-004 / RPV-007

I believe there were several variations on it but am not certain.

There are some good photos of it flying in the SDASM collection

Benson also had a patent on an XD-110 vehicle:

"Aerodynamic flow body"

US4033526A - Aerodynamic flow body - Google Patents

Disclosed is an increased lift aircraft or similar device having an airfoil shaped forward structure. A mass flow engine, such as a jet engine, is positioned to the rear of this structure. In operation, the intake air flow for the engine flows around the forward structure, generating lift.
