Abstract
A starter for a piston aircraft engine is constructed by placing the pinion-gear and drive clutch, the engagement solenoid and the driving motor in a linear arrangement, the motor driving the clutch via a geared shaft passing by the engagement solenoid. Such construction provides minimum diameter for a solenoid-engaged piston aircraft engine starter in order to fit the available space on existing aircraft originally designed to be equipped with centrifugally-engaged starters.
Claims2
A starter (cranking motor) intended for the cranking of an aircraft piston engine equipped with a ring-gear for such purpose, said starter incorporating (a) a pinion-gear driven by a one-way clutch drive assembly, (b) an electromechanical engagement solenoid containing a plunger which pushes said pinion-gear into engagement with said engine's ring-gear without intervention of any lever-arm,
- (c) a DC motor which drives said pinion-gear via said one-way clutch drive assembly through (d) a geared shaft that provides gear reduction between the armature of said motor and said one-way clutch drive assembly, said electromechanical engagement solenoid located between said one-way clutch mechanism and said motor, said geared shaft passing by said solenoid.
