I don't think we should necessarily direct our members to the SPF forum, especially if we consider that some of the topics there need registering to be seen. Why not republish the information, or part of the information here?

Anyway, here are a few rotorcraft projects from Bristol:

1°) Bristol 208 (for GOR.351) and 224 (for NBMR.4) V/STOL projects

2°) Bristol 217 VTOL strike recce aircraft (for OR.345)

3°) an unidentified tandem rotor helicopter assumed to be from Bristol

4°) Bristol 194 "BEA Helicopter" developed from Type 192

5°) Bristol 194 "BEA Helicopter" developed from Type 192

6°) Bristol 194 "BEA Helicopter" developed from Type 192

7°) Bristol Siddeley "Jumping Jeep" model

8°) Bristol single-rotor helicopters in profile

9°) Bristol tandem-rotor helicopters in profile

10°) Bristol helicopters specifications
