Deltic engine. Still in use in some minesweepers. :) Used because of the high power to small size. Unfortunately the governors were cr*p and the engine used to run away lol.

 

Yup, Napier Deltic as used in class 55 locos.

only ten minutes, not bad :friday:

Deltic 160cc?

neat:d

I always wondered if one could be scaled down sufficiently to use in a model aircraft (probably but at what cost?) Means you could adjust the gearing from the cranks to suit the airscrew.

so not a flux capacitor then, no? :( I was so excited then :D

 

nope, but I do have a working model of a 'flux capacitor' in my shed, I'll tell you about it last week. :D

if you want ultimate high performance piston engines its got to be the Napier Sabre it powered the WW2 Tempest and Typhoon the Tempest being the fastest low level strike aircraft of the war, the Sabre had sleeve valves that ran the length of the piston rather than the traditional popet valves seen in our cylinder heads this lead to a very compact design, late war models produced 3750 hp which was power Rolls-Royce could only dream about and to proove the reliability Napier ran a Sabre at the full power of 3750 hp for 175 hours none stop, imagine the cost of V-Power today on a 37 litre motor ran at full power for a week :blink:, now if i can just squeeze one in the back of the supe :eyebrows:

100 horsepower per litre from an n/a, should get the twin turbo guys thinking a bit !

 

BUT

 

Packard/Merlin engined Mustangs were still better at altitude.

Wow.

Thats awesome.

 

It would be interesting to know the cost of that test in todays modern robbing fuel prices.

Are there any aviation buffs who have got an idea of the consumption of one of these beasts :search:
