Hi,

I found this Parnall light military general-purpose monoplane
project in Flightglobal,but I don't know if it was a project or
it built after 1936 ?.

Re: Parnall light military general-purpose monoplane

"light military general-purpose monoplane"? ???

I guess it's a "scout-dive boming monoplane" as the USN would put it.

Re: Parnall light military general-purpose monoplane

To me "light military general-purpose monoplane" sounds more like a more
modern version of, say, the Westland Wapiti, tasked with army cooperation,
recce and maybe light attack in the case of policing actions, so what
nowadays would be called a COIN a/c .

Re: Parnall light military general-purpose monoplane

There's a bit more info on page 512 of the mentioned Fight file.
Projects should be a development of the civil Parnall 'Heck'.

Re: Parnall light military general-purpose monoplane

Nice find, Hesham!

The spats give the look of the later Type 382 Heck Mk III trainer. I'd imagine that the family resemblance would be even stronger for the two Hecks used to test the smaller Wolseley Aries radial engines.

The 1936 date probably tells us why this project never proceeded. IIRC, that was the year Wolseley decided to stop producing aircraft engines. I suppose that a 240 hp AS Lynx might have been substituted.

Re: Parnall Type 382 « Heck » Mk.III

Hmmm, it looks like a Miles type of some sort, but the tail fin
appears to have been altered. Will check the putnam, later...




cheers,
Robin.

It's a Parnall Type 382 Heck Mk.III, I think, from 1938.

Re: Parnall Type 382 « Heck » Mk.III

Thanks also, Jemiba, saved a long fruitless search through the 'Miles' book.
(But you can see where I was coming from...)

Some more. Developed from the Parnall Heck 2C cabin monoplane. and
also known as the Heck Mk III, the Parnall type 382 was designed to
Specification T.1/37, which called for an elementary two-seater trainer
larger and heavier than the Hawks and Magisters then in service. The
engine was specified as the DH Gipsy Six, of 200hp.
The type 382 was favourably evaluated by the A & AEE, particular attention
being given to the types' interconnected flaps and slats, a first for a
primary trainer. However the T.1/37 specification was not proceeded with,
neither the type 382, nor the Miles M.15, being produced in quantity.
At first flying with the Class B marking J1, the type 382 was registered
G-AFKF, before being impressed as R9138. In 1943, it became Ground
Instructional Airframe No. 3600M, being scrapped before the war's end.


Source, Putnam's 'Parnall'




cheers,
Robin.

Re: Parnall light military general-purpose monoplane

A bit more on this in Flight 12 Nov 1936 issue...

PARNALL AIRCRAFT, LTD., of Yate, Gloucestershire,
have designed an interesting little military general-purpose
type developed from their Heck civil two-seater described
in the appropriate section of this issue. A Wolseley Scorpio
II engine of 260 rated h.p. was originally specified and was
estimated to give a maximum speed of 199 m.p.h. at 8,000 ft.
The following alternative armament installations are provided
for: rear gun and two front guns; rear Lewis gun and two
120-lb. bombs; or rear Lewis, gun and eight 20-lb. bombs.
The fixed front guns are installed in the wings. Dual control
can be fitted in a very short time, so the machine would lend
itself to advanced training in a large air force, or could be
used purely as a fighting or bombing type by impecunious
buyers.

Hi,

maybe this aircraft Project was a private venture to Spec. G24/35 ?.

Re: Parnall light military general-purpose monoplane

Unlikely, far too small and underpowered. I think that is was a speculative design to benefit from the work done on the Heck and maybe aimed at the overseas market

Re: Parnall Light Military General-Purpose Monoplane Project

This is very soon after George Parnall sold his company,George Parnall and co, to Nash and Thomson and was merged with Hendy to become Parnall Aircraft Ltd. George Parnall and co had not built an aircraft of their design for some time (they were carrying out Hawker Demon turret conversions) so I guess the new management were keen to promote the design capabilities of the new company, and a good way to do this was to produce speculative designs based around Hendy's products. I would suggest that this sketch is just such a concept and the Heck MkIII, built as a trainer to spec. T.1/37, may have started the same way.

I think this conclusion maybe solve the problem.

No, its actually the other way round. The Type 381 was originally designed as a simple test airframe for the low-profile turrets but was 'upgraded' to be more like a twin-engined fighter.

Re: Parnall Little Known Projects

You're not going to give up on this are you? There is no evidence from any of the informed sorces for a project with this name, which would not fit any of Parnall's naming systems and is not even a word in English. You have to provide us with more information about where you found the project so that we can have a look and see if we can understand. Like the Fuffin/Puffin confusion there is probably a simple explanation

Re: Parnall Little Known Projects

Well its the usual and obvious warning, don't believe everything you find on the internet. A single source is never good, if you can't remember what that source was, that's even worse. Most likely it was just a mistake.
