Planet Aircraft Ltd and Firth Helicopter Prototypes
« on: December 09, 2006, 12:55:09 pm »
Hi folks,

Thought I would post these pics etc on the Planet Satellite light aircarft of the late '40s.  It was a four seater built of magnesium alloy,retractable undercarriage fitted with a Gipsy Queen 32 amidships driving a pusher airscrew in the tail,designer was a Mr J.N.D.Heenan,she was built in the Robinson Redwing factory at Croydon,Purley Way,Surrey in 1947,taken to Redhill in 1948 and shown at the S.B.A.C show at Farnborough in September 1948,took up the registration G-ALOI in April 1949,failed to get airborne at Blackbushe despite several long runs down the runway,thus any further attempts to fly her were abandoned.

Span 33 feet 6 inches,Length 26 feet 3 inches,Tare weight 1,600 lbs,all up weight 2,905 lbs,max estimated speed 208 mph,cruise estimated at 191 mph.  (More info can be found in Bill Gunston's "Back to the Drawing Board")

No known drawings exist.




Regards,

Greg

There was a drawing in a wingspan issue, can't tell in the moment
which it was, but I used it as the basis for my drawing

Perhaps we should add, that this helicopter, built by Firth Helicopter and
designated FH.01/4 Atlantic, used the fuselage of the second Planet
prototype ...

Thanks GTX, this is a good candidate I had forgotten for the title of "most beautiful aircraft in the World"...
Thanks Jemiba, your drawings has been a very good basis to invent Satellite-Mustang mixes of mine (see http://www.whatifmodelers.com/forum//index.php?showtopic=4461&st=360&#entry185090 ) ;D

Maybe its sounds stupid, but this plane looks a bit like the bugatti-100 racer of the 30's...  ???

You're quite right, but there are a number of other aircraft or
at least projects. For example this patent from Miche Wibault,
for a sports a/c with a pusher prop. Form follows function ...

Maybe it's just me, but this one always made me wonder if it inspired the lines of the BD-5.

There's a good writeup of the project if you are interested.

hmmm...I know it from a reference book called "Macchine bizzarre nella storia dell'aviazione" by Giorgio Evangelisti, but can't remember the name. If no one identifies it by tomorrow I'll dig it out. So rest assured one way or another the mistery will be solved! ;)

All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

I've seen it before, but where? British I think. Miles-related perhaps?

It reminds me of the Bugatti 100 racer, but with the prop on the other side!

Beautiful design either way!

"Anyone know what it is?"

It's the Planet Aircraft Ltd. Satellite from 1946, which, I think, made just one
short flight and was structurally damaged during the landing. So the project
was shelved, but the fuselage was "recycled" for the Firth Helicopter FH.01/4
Atlantic later.
There was an article in "Wingspan", whose interested in it, just drop a PM.

That's two flying machines I'd never heard of. Educational forum this!  ;)
Thanks very much, very interesting.
It's clear the Satellite lost its ventral fin during that landing!  :-[
