Patent number: 8800918Abstract: A system for generating accessory power from a gas turbine engine is provided by the present invention. The system includes an electronic control device for monitoring at least one parameter which provides information about an incipient change in power demand, a control valve operated by the control device for supplying bleed air from the engine during a transient state in response to the at least one monitored parameter, and a pneumatically operated device for receiving the bleed air and for generating power to operate equipment onboard an aircraft. The pneumatically operated device may be an air turbine or a pneumatically integrated generator.Type: GrantFiled: March 30, 2009Date of Patent: August 12, 2014Assignee: United Technologies CorporationInventors: Timothy M. Morris, Wayne R. Spock, Peter Gerard Smith, Matthew J. Schryver, Ronald S. Walther, Robert L. Gukeisen, Edward T. Hagaman

Patent number: 4722061Abstract: In an electronic engine control (EEC) for a turbine engine, a high rotor speed signal (N2SYNTH) is synthesized from a sensed low rotor speed signal (N1) in a primary control channel (32) so long as the low rotor speed signal is healthy. If the low rotor speed signal (N1) is not healthy, the primary channel is reconfigured (FIG. 3) so that a low rotor speed signal (N1SYNTH) is synthesized from a sensed high rotor speed signal (N2).A secondary control channel 34 provides standby signals for use in the EEC and performs similar logic as in the primary channel, except that signal synthesis (N2 from N1 and vice-versa) is dependent upon N2 health. When the high rotor speed signal (N2) is healthy, a low rotor speed signal (N1SYNTH) is synthesized from a sensed high rotor speed signal (N2). When the high rotor speed signal (N2) is not healthy, a high rotor speed signal (N2SYNTH) is synthesized from a sensed low rotor speed signal (N1).Type: GrantFiled: December 20, 1984Date of Patent: January 26, 1988Assignee: United Technologies CorporationInventors: Larry B.

Patent number: 4651518Abstract: By utilizing compensating parameters required for steady state operation of a gas turbine engine with processed variables of compressor speed, compressor pressure and altitude a derivative of the variable desired is synthesized and compared to the actual value in a closed-loop system for limiting the rate of change of fuel flow in an engine transient condition. In a twin spool engine a function generator responding to speed of the low pressure compressor and altitude generates a signal indicative of rate of change of the speed of the high pressure compressor. The signal is compensated for time constants consistant with the dynamics of the engine and compared with a compensated actual high pressure compressor speed. The error produced with a gain generated from corrected high pressure compressor speed inputs the main electronic digital fuel control.Type: GrantFiled: December 18, 1984Date of Patent: March 24, 1987Assignee: United Technologies CorporationInventors: Peter W. McLaughlin, Wayne R. Spock, David F. Kenison

Patent number: 4641517Abstract: Redundant sensed position feedback signal samples of an actuator which are provided in each sample period, a synthesized feedback position signal value provided from an actuator algorithm model. The sensed samples are rejected for use in the sample period if the difference magnitude between the sample value and the synthesized value exceeds an accepted magnitude. The number of sample periods in which a sample is rejected is recorded, and if the number is sufficiently high the sensed feedback signal is rejected from further use and the associated position sensor is recorded as failed. If both sensed samples are rejected in the same period a diagnostic routine determines if the fault is in the sensors or the actuator.Type: GrantFiled: December 20, 1984Date of Patent: February 10, 1987Assignee: United Technologies CorporationInventors: Wayne R. Spock, Peter J. Urbanik

Patent number: 4639885Abstract: Periodic digital signal samples of redundant sensed engine RPM signals are rejected for limit exceedance of known performance values, the nonrejected digital signal samples are each compared with a synthesized RPM equivalent signal to further reject any sample which differs from the synthesized value by more than a selected difference value, one of the nonrejected samples are then used for the engine RPM indication, and in the event that both samples are rejected the synthesized value is used.Type: GrantFiled: December 24, 1984Date of Patent: January 27, 1987Assignee: United Technologies CorporationInventors: Wayne R. Spock, Richard P. Meisner
