Aircraft engine starting - Wikipedia
Hand starting of aircraft piston engines by swinging the propeller is the oldest and simplest method, the absence of any onboard starting system giving an appreciable weight saving. Positioning of the propeller relative to the crankshaft is arranged such that the engine pistons pass through top dead centre during the swinging stroke.
Hand-Propping Demystified - AVweb
2015年3月29日 · The best and safest planes to hand-prop are ones that require it by design. Old-school planes like Champs, Cubs, Luscombes and Taylorcraft of a certain vintage fall into this category, as do a number of ultralights and even some modern light sport models. If you want to learn how to hand-prop a plane, this is the category to start with.
Turboprop and Turbofan Engines Starting Procedures - Aircraft Systems
Most turbofan engines can be started by either air turbine or electrical starters. Air-turbine starters use compressed air from an external source as discussed earlier. Fuel is turned on either by moving the start lever to “idle/start” position or by opening a fuel shutoff valve.
Engine starting schematic for a light twin-engine aircraft. The typical starter motor is a 12- or 24-volt, series-wound motor that develops high starting torque. The torque of the motor is transmitted through reduction gears to the overload release clutch. Typically, this action actuates a helically-splined shaft moving the starter jaw outward

Hand Propping an Aeroplane - KITPLANES
2016年4月21日 · Propping was an easy procedure for low-compression engines installed in tailwheel airplanes, where swinging the blade used the leverage of a head-high propeller hub. It was always expected that a knowledgeable individual, capable of holding brakes and manipulating ignition and throttle, would be in the cockpit.
The Evolution of Engine Starting: From Hand-Propping to
2015年3月6日 · When the engine started, the pilot would then resume control of the airplane; adjusting the throttle for proper idle, switching on a second magneto, checking oil pressure, and completing the start procedure from memory. Here is a great video of someone hand propping a 985 cubic inch radial, safely and without theatrics.
Hand Propping Tips - JoeA
Electric start airplanes frequently have the prop mounted in a bad position for propping. If they have key type starting you would have to disconnect the starter or unwanted ignition or starter engagement may occur.
