The Midwest twin-rotor wankel engine has an eccentric shaft that spins up to 7,800 rpm, so a 2.96:1 reduction gear is used. Aero-engine reduction gears are typically of the gear type, but smaller two-stroke engines such as the Rotax 582 use belt drive with toothed belts, which is a cheap and lightweight option with built-in damping of power surges.
Higher compression ratio (6:1) and maximum RPM for racing use. Gipsy Major ID Fuel pump added, plus screened ignition harness and priming system. Gipsy Major IF Aluminium cylinder heads, 5.25:1 compression ratio. Gipsy Major II Variable pitch propeller Gipsy Major 7 Military version of Gipsy Major 1D, increased climb RPM. Gipsy Major 8
The main drawback is that a special type of electric motor is often needed to provide high torque outputs at low rpm. Compared with a multi-speed transmission, the motor is usually operating in its optimal power band for a smaller range of output speeds for the system (e.g., road speeds in the case of a motor vehicle).
The Tee Dee was tested by Aeromodeller Magazine in 1962 and the output power was recorded to be .105 bhp (78 watts) @ 22,000 rpm with a max torque of 5.5 oz.in. at 18,000 rpm on 25% Nitro. [20] (Note: The modern Norvel AME 049 engine which has an aluminum piston running in a ceramic coated cylinder, outputs .14 bhp (100 watts)@ 20,000 rpm).
A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant. [1] This allows the use of small displacement internal combustion engines to turn aircraft propellers within an efficient speed range.
