Propeller drive system for motorized glider has internal combustion engine buried in fuselage, with retractable propeller on swiveling mounting

摘要

The internal combustion engine (1) is mounted in the tail end of the fuselage (5). It has a mounting (8) which allows swiveling through a small angle (26). A carrier strut (7) at the front of the engine carries the pulley wheels for a chain and belt reduction drive system (2). There is a belt drive (9) for the propeller (3) with a drive pulley (10) on a swiveling (13) bracket, a belt (12) and a driven pulley on the propeller shaft. The propeller shaft is mounted on a swiveling frame (4).
