Hi all,

these two pictures I have found on the net. Please give some technical data and drawings if you can.

Thanks Maveric

The P.91 was a tip jet powered 2-seat (very) light helicopter, dsigned in 1954 to
meet the H.144T specification, which was won by Fairey Ultralight.

The P.105 was intended as a 10-seat derivative of the P.74. But when the
P.74 became a total failure, unable to lave the ground, the P.105 was
cancelled, too. A flying crane version was proposed, which then disappeared
together with the basic version.

all-metal design,powered by Napier N Or.101 turbo gas generators with a freely tilting twin-bladed rotor

Interesting concepts. Were there any more of these projects?

Dear Wyvern,

you will find them in this book;
On The Wings of A Gull (Percival and Hunting Aircraft)
