[Norse]

I'm also looking for pics of this proposal for the dart Harold?

 

[Norse]

Is a version was also turbo fan powered?

Never built, proposed engines two R-R RB.183 Spey Junior turbofans.
In Handley Page Aircraft since 1907 by CH Barnes, Putnam 1987 edition revised by Derek N James, the H.P.R.6 is described as a proposal for a Vickers Viscount replacement with four R-R Tyne turboprops.
Of the H.P.R.7 Dart Herald, 50 were built.

Okay thanks

Four engine turboprop?

 

[Arjen]

Yes.
H.P.R.6 - 4 x Rolls-Royce Tyne, laminar-flow wing, blown flaps, project only.

 

[Norse]

So no pictures?

 

[Arjen]

No pictures.
Stuck on the drawing board by Richard Payne, Tempus 2004, has a note on the H.P.R.6: "powered by Rolls-Royce RB109 Tyne engines, and later possibly with twin Conway engines".
The Rolls-Royce Conway is a turbofan.

Okay thanks

Kind of interesting last projects for a company.

I guess it would look kind of like this this is a Fokker airliner

 

[Norse]

Kind of wondering what a four engine de Havilland Canada dash 8 will look like oh wait I don't have to

 

[Norse]

Man this was a popular configuration of airline with turboprops.

Not really.

The Fokker-VFW P.301 was to have 4 x lightweight PT6A-50s ... making it more like a lower-powered DHC-7. The turboprop H.P.R.6 was to have 4 x Rolls-Royce Tynes - each with 4-to-5 times the power of those little Pratts.

Likewise with turbofan variants. The Fokker P.305 was to have twin ALF 502s (like a bizjet), the H.P.R.6 (as Arjen noted) was to have 2 x much larger Rolls-Royce Conways.

As for the Dash-7, it achieved STOL through full-span, double-slotted flaps (along with the prop discs covering most of the wing span). The H.P.R.6 was to have blown flaps.
