High compression diesel engine helicopter
WebCompared to a gasoline (petrol) engine, a diesel engine has a very high compression ratio, an essential design feature, as it is the heat of compression that ignites the fuel. An electric starter with sufficient power to "crank" a large diesel engine would itself be so large as to be impractical, thus the need for an alternative system. WebThe indispensable diesel engine performance for an ideal helicopter platform has been established to satisfy the requirements. The maximum power as a function of height is given below (Fig....

WebThis paper describes an investigation of the effect of compression ratio on engine efficiency over a range of compression ratios from 9/1 to 25/1. The results show that the thermal efficiency of the multicylinder engines used in this study peaked at a compression ratio of 17/1. The decrease in thermal efficiency at higher compression ratios is ... http://www.redbackaviation.com/helicopter-engine-options-diesel-helicopter-engines/

It seems like there would be substantial engine damage. The sudden increase in pressure on the piston (from premature detonation) would likely put a lot of stress (torque) on the crankshaft. great questions to ask the interview panelWebThe GM XM1 had a new variable-compression diesel engine which was very troublesome in testing, while the Chrysler XM1 used the rather thirsty Honeywell AGT1500 gas turbine power plant that was originally planned to power helicopters. great questions to ask your mentee
