Bristol Pegasus

I thought the only dutch twin engined aircraft that i can think of used Mercury engines in stead of Pegasus engines?

Think again?:D

Cees,

I only know of two surviving in Australia, both are in museums, one is in an airframe, I assume they are few and far between elsewhere, however the BAPC lists 24 in the UK?

I have always thought these to be rarer than rocking horse – s#*t or is that flying horse S#*t – smiles, and I assume the twin re-creation you refer to will need 2 engines? perhaps its better to try get access to one to create a fibreglass casting of the front of the crankcase/nose and cylinders? and build two dummy engines?

Thanks John,

So have I but these enquiries are not for me but for someone who intends to start a fullsize Fokker T V twin-engined bomber.

Hi Cees

I’ve got an original Pegasus manual if you’re interested

That’s a different project: http://www.fokker-g1.nl/

A fullsize “luchtkruiser” ???

Same crankcase and reduction gear, rocker mech, cyl heads and back end. Basically the Mercury was a short stroke “racing” Pegasus.

Apart from the barrels, conrods and valve pushrods/shrouds and a few other detail differences it was basically the same engine.

If you can get yourself a couple of non-runner Mercury engines from Canada you could have new barrels machined and dummy up the pushrod covers etc. and, hey presto, a Peggie:D

Hi Anon,

Why Mercury’s from Canada, are there many available there?

Hi,

As far as I know the Pegasus was very similar to the Mercury. IIRC the stroke of the first one was 1 inch longer than the Mercury. So perhaps many parts of a Mercury could be used. There is also a very interesting Dutch twin engined aircraft from that time that had no Mercury engines:confused:

Mercury engines

The Mercury engine is almost as rare here as the Peggie – except for the fact that ARCo at Duxford are/were reputed to have a few spares made up from a large batch they imported from Canada when they got the Blenheims.

The rumour I heard about 15-20 years ago was that they imported a load of Mercury engines (approx 20?), used them to recoved flyable parts for the Blenheim project and spares and scrapped what was left. If that did happen then it was a disgrace. Can anyone confirm or deny this?

Like many things Stateside/Canadian there always seems to be lots of vintage stuff sitting in barns etc. The Canadian Blenheims (and other types including Lysanders, which used the Mercury engine) were sold off in their droves after the war to scrappies and farmers, who bought them for the fuel they contained and the hardware, the remains often being consigned to a barn where they were eventually re-discovered. The same goes for engines, many of which survived for the well-worn reason that one day they were going to be fitted into something agricultural.

The ex-Canadian Blenheim (Bolingbroke) airframes that were subsequently discovered and rebuilt were many as also were their Mercury engines – many airframes still havng them fitted. Plenty survived to supply the restorers and I am presuming that there are quite a few still out there – both in museums/collections and in the barns scattered throughout the prairies.

Perhaps some of our Canadian friends can confirm this? If it is the case then, as suggested earlier, Canada’s the place to go for ’em.

Well, with the will to get the engines you want anything is possible. The chap in question has only just started to get into it so he says. Time will tel how serious he is.
