Assignee:

AEROMECHANICAL SERVICES LTD. - Calgary AB

International Classification:

B64D 43/00

US Classification:

701 3

Abstract:

An automated aircraft flight data and delivery management system and method operates in a normal state and a demand state. The demand state may be self-initiated or manually-initiated, and may be triggered during situations which include but are not limited to situations when the aircraft is in a potential or confirmed emergency situation. Data transmission increases in intensity when the system is in a demand state.

Abstract:

Disclosed is a system and method for minimizing vibration over the full operating range of a rotor of an apparatus. The system includes a transducer or an array of transducers for resolving up to six degrees of freedom of motion of a rotor support structure. In one embodiment the transducer is a six degree of freedom accelerometer located near the center of gravity of the structure. In addition to the motion transducer, a shaft position reference sensor is connected to the shaft of the rotor and/or rotor support structure. A signal processor that receives signals from the transducer and the shaft position reference sensor produces Fourier coefficients of motion occurring in each degree of freedom. The system utilizes analytical models or empirically derived data to describe the Fourier coefficients of acceleration (or strain) resulting from each of the available rotor adjustments. The system and method also utilizes an analytical or computational optimization scheme which computes the best combination of rotor adjustments to meet criteria specified by the user.
