My dear Jemiba,

can I ask you if there was a project to Hawker called HS-810
VTOL transport aircraft or not ?.

Acording to R.Payne "Struck on the Drawing Board", the HS.810 was a Circulation Control
Rotor designs, with rotors at the wingtips, powered by four RS 660-06 in two pods. Forward
thrust was provided by three RB 211. The concept was axed, because maximum speed was
limited to Mach .70 .

And if you look at the "VTOL port" you see where the whole idea fell apart.
By the time you have a site that big, no big deal to add a 2000 foot runway and operate a quiet STOL aircraft instead.

Barrington Bond said:
Twin Pegasus VTOL Strike aircraft - number unkown to me at the moment.

Is the second Pegasus mounted back to back but with the rear one pointing backwards? that reminds me of Dan Raymer's RIVET (something like reverse installation vectored thrust...). i thought he had a patent on it, but this seems to precede it.

From Air Enthusiast Vol.1 No.1 dated June 1971, the Hawker Siddeley H.S.803 compound project, which I couldn't find elsewhere on the forum.

Yep, thanks for the picture and for the date - definitely precedes Raymer's.

Good stuff. Never seen or heard of this before. I wonder what the cross-sectional area distribution of this configuration looks like. Might have some transonic advantages.

It would also have reduced 'suck down' with the canard/wing not over the main jets in vertical flight.


Interesting that it shows Sparrows on a UK design of the time. Trim change on missile firing would have been fun!

A modification of the Nord Noratlas (maybe based on the N.2508, because of the auxiliary wing tip jet engines)
by fitting lift engine pods was proposed by Hawker Siddeley during 1966. The nose spike would have housed the
forward puffer jet. The type wasn't meant as an operational type, but for development according to NMBR.3.
(from Der Flieger, May 1966)
