Abstract

A simulator handgrip is connected to the shaft of a slip clutch which offers resistance to handgrip displacement, thereby simulating the "feel" of an actual thrust control for aircraft. Linkages are provided for measuring the amount of handgrip displacement as an electrical signal that may be utilized by a simulator computer. Adjustment devices are provided for moving the handgrip and clutch devices along a diagonal direction to accommodate pilots of different height.

Claims

1. An aircraft thrust control simulator comprising:

a handgrip having a mounting shaft;

a slip clutch having a shaft extending transversely of the handgrip shaft and connected thereto for imparting preselected friction in response to displacement of the handgrip;

linkage means connected at a first end to the handgrip shaft for translating handgrip displacement to a corresponding linkage displacement;

transducer means connected to a second end of the linkage means for electrically measuring the handgrip displacement;

a support means for mounting all of the above-indicated means;

a pair of parallel spaced threaded rails mounting the support means;

adjusting means connected to the rails for threadingly screwing the rails relative to the support means thereby displacing the handgrip to a position particularly suited for a pilot.

2. The structure set forth in claim 1 together with a semi-cylindrically notched plate juxtaposed against the slip clutch and through which the handgrip extends, the plate notch having an irregular pattern requiring compound displacement of the handgrip along the notch thereby simulating afterburner energization of a jet aircraft.
