A hybrid power module efficiently delivers both hydraulic power and electric power. The hybrid power module may regenerate and store energy for later use. The module includes and engine and an electric motor for driving a hydraulic pump. The electric motor is operable as a starter motor for the engine and as an assist motor cooperating with the engine to power the hydraulic pump to improve dynamic response of the hydraulic pump. The module also includes an electric power source which may have an energy storage unit, and the electric motor may be operated as an electric generator providing electric energy to the energy storage unit.

The present invention provides an algorithm that does not relax the problem at the very onset, even if xis infeasible. Instead, it solves the EQP with the initial guess for the active set without relaxing the problem. If this solution to the first EQP is not optimal, but nevertheless feasible, we can use this as our guess for the feasible point. This has the advantage of being a feasible point that is consistent with the initial active set, whereas the initial guess used in the previous method is not necessarily so.

A plurality of wires ( ) are disposed near the bottom ( ) of blade root sockets ( ) of a rotating disk of a gas turbine engine by vapor deposition and etching, the wires including connections to excitation nodes ( ) and detection nodes ( ). A nearby stationary member of the engine mounts an oscillator amplifier ( ) which drives a coil ( ) that excites the circuitry, and a coil ( ) drives an amplifier ( ) and a processor ( ) which provides an indication of whether or not one or more of the wires are broken by a crack.

An apparatus for use in a system having a gas fuel supply and a combustor includes a fuel actuator, a controller; and a premixer. The controller generates a command signal indicative of actuation sought from the fuel actuator. The actuator receives gas fuel from the liquid fuel supply and provides liquid fuel at a modulated rate of flow in response to the command signal. The premixer receives the fuel from the actuator, mixes the fuel with air, and provides the mixture to the combustor.

The present invention teaches a system for improving the clarity of a voice spoken within an enclosed space. The system comprises a first microphone, positioned at a first location, for receiving the audible communication and for converting the audible communication at the first location into a first audio signal. The system also comprises a loudspeaker for receiving the first audio signal, and for converting the first audio signal into a first reproduced audible communication, the reproduced audible communication also being fed back and received by the first microphone and converted with the audible communication into the first audio signal. Moreover, the system comprises an acoustic echo cancellation system for determining the relationship between the received audible communication by the first microphone and the first audio signal comprising both the audible communication and the reproduced audible communication fed back to the first microphone, and for removing the first reproduced audible communication fed back to the first microphone from the first audio signal received by the loudspeaker.

A modular vibratory force generator (10) is adapted to be mounted on a helicopter fuselage (11) and operated to selectively apply a controllable vibratory force (F.sub.R) thereto. The improved generator includes a plurality of force-generating modules (12, 12) and a closed-loop servocontroller (13). Each module has a pair of counter-rotating eccentric masses (20, 21) that are arranged to exert a fixed-amplitude variable-phase individual force at spaced locations on the fuselage. These individual forces (F.sub.1, F.sub.2) combine to exert a controllable-amplitude resultant vibratory force (F.sub.R) on the structure. The servocontroller is adapted to be supplied with a single sinusoidal control signal and is operative to cause the frequency and phase of the resultant vibratory force to be identical to the frequency and phase of the control signal and to cause the amplitude of the resultant vibratory force to be proportional to the amplitude of the control signal.

Modular vibratory force generator, and method of operating same

An actively-controlled resonant-type force generator (20) is adapted to be attached to a structure (21), and includes a mass (23) mounted for movement relative to the structure and a plurality of springs (22, 24) operatively arranged between the mass and the structure. A servoactuator (26) is arranged to controllably excite the mass-spring system. The actual force (F.sub.a) transmitted from the mass to the structure is compared with a commanded force (F.sub.c) to produce a force error signal (F.sub.e). The actuator is caused to produce a velocity as a function of the error signal. The gain of the closed force loop is selected so that the resonance of the mass-spring system has an effective damping ratio (.zeta.) greater than about 0.5, and preferably about 0.7. Thus, the mass-spring system will not be substantially resonantly excited by vibrations of the structure near its resonant frequency (.omega..sub.n).

Method and apparatus for actively adjusting and controlling a resonant

A device (19) for generating a rotating force vector and an oscillatory couple includes a plurality of non-concentric eccentric masses (22A, 22B, 22C, 22D, 22E, 22F) co-rotating at the same angular speed; and means (24A, 24B, 24C, 24D, 24E, 24F) for individually controlling the angular position of each of the masses; whereby, by selectively controlling the angular position of each eccentric mass, the device may generate a desired rotating force vector and a desired oscillatory couple. In use, the device performs an improved method for opposing the propagation of vibration from a dynamically unbalanced rotating rotor through a supporting structure (12). This method comprises the steps of: mounting a plurality of non-concentric rotatable eccentric masses on the supporting structure; co-rotating each eccentric mass at the same angular speed as the rotor, and controlling the angular position of each mass relative to the angular position of the rotor; thereby to generate a pattern of rotating inertial forces to oppose the transmission of vibration from the rotor through the supporting structure.
