Abstract

A locking mechanism for the tail rotor of a stationary helicopter comprises a central body (10) having a fastening device for each individual rotor blade (1, 2). Such a mechanism serves to secure the rotor blades (1, 2) against the effects of wind. A regulating mechanism for the rotor blades (1, 2) includes the so-called tail rotor star (9). The invention has been to provide a locking mechanism which also is easy to fit and to remove. Thus, said central body consists of a tubular hollow body (10) which, at one end thereof, is provided wiht indentations (11) and, at the opposite end, carries fastening straps (12, 12') with buckles (14, 14'). The indentations (11) correspond in shape, number and position to the design of the tail rotor star (9) which, thus, serves to regulate the positioning of the central hollow body (10) of the locking mechanism, one strap (12, 12') being arranged for each rotor blade (1, 2).
