The Hucks starter (invented by Bentfield Hucks during WWI) is a mechanical replacement for the ground crew. Based on a vehicle chassis the device uses a clutch driven shaft to turn the propeller, disengaging as the engine starts. A Hucks starter is used regularly at the Shuttleworth Collection for starting period aircraft.
A jump start, also called a boost, is a procedure of starting a motor vehicle (most commonly cars or trucks) that has a discharged battery. A temporary connection is made to the battery of another vehicle, or to some other external power source. The external supply of electricity recharges the disabled vehicle's battery and provides some of the ...
An early axial compressor turbojet had an ATS located in the compressor nose cone (eg particular variants of the J79). Air impingement starting was not used for US military aircraft after the F-4B, A-5A [6] and F-5 as the pneumatic energy requirement was several times greater than when using an air turbine starter. The gas turbine compressor ...
An auxiliary power unit ( APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the ...
Step 1: Park the second vehicle close to the one that needs a jump. Park the car with the good battery nose to nose with the one needing a jump, close enough that the jumper cables will reach ...
The power gets shunted into the battery, and no torque is supplied to the wheels. The onboard computer does this when required, for example when stopped in traffic or to warm up the engine and catalytic converter after a cold start. Engine start: To start the engine, power is applied to MG1 to act as a starter. Because of the size of the motor ...
An electric starting system was not possible due to the limited capacity of the cooling system, so the chemical ignition system was used. [ 70 ] On a typical mission, the SR-71 took off with only a partial fuel load to reduce stress on the brakes and tires during takeoff and also ensure it could successfully take off should one engine fail.

A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
