The outlet of a secondary air separation module (one or more ... 03/01/07 - 20070049188 - Aircraft cabin pressure control system and method for reducing outflow valve actuator induced cabin pressure oscillations A cabin pressure control system and method that reduces or inhibits gear train backlash and the concomitant cabin pressure oscillations associated therewith. The cabin pressure control system includes a variable proportional-integral (PI) controller that implements a proportional function with a variable gain term and an integrator function with variable saturation ... 02/22/07 - 20070042697 - Outflow valve having a cable operated closure mechanism An outflow valve includes a valve closure mechanism that automatically closes the outflow valve in the unlikely event the outflow valve actuator becomes inoperable. The valve closure mechanism includes a pulley, a load plate, a cable, and a spring. The pulley is coupled to a valve element is the outflow ... 11/09/06 - 20060252360 - Aircraft cabin pressurization control apparatus A cabin pressure control apparatus that has an outflow valve that operates with a reference chamber without the need of using bleed air from the aircraft engines to adjust the pressure within the reference chamber. The invention has only pneumatic connections and no electrical connections to the outflow valve. Intrinsic ... 09/21/06 - 20060211359 - Cabin pressure control system and method that accommodates aircraft take-off with and without a cabin pressurization source An aircraft cabin pressure control system implements control logic that significantly reduces potentially uncomfortable pressure bumps that can occur during aircraft take-off rotation both with and without cabin pressuring fluid flowing into the aircraft cabin. The control logic implemented by the cabin pressure control system, among other things, determines whether ... 04/06/06 - 20060073780 - Airflow control system A dual airflow control system for an environment having a first air zone and a second air zone. The system includes a first input device operable to generate a first input signal indicative of a desired airflow to the first zone and a second input device operable to generate a ... 02/02/06 - 20060025064 - Aircraft modular cabin pressure regulator One embodiment of the invention relates to a modular cabin pressure regulator that can receive its destination parameter and control settings from an avionics system or a manual selector and display. The modular pressure regulator includes a removable selector, a controller, and a monitoring unit to control an electromechanical actuator ... 01/26/06 - 20060019594 - Cabin pressure control system and method A cabin pressure control system and method includes one or more dual-channel controllers. One of the channels is a primary channel and the other channel is a secondary channel. The primary channel includes two dissimilar cabin pressure sensors and a controller that is used to modulate the position of an ... 07/14/05 - 20050153648 - Cabin pressure control method and apparatus using all-electric control without outflow valve position feedback A pressure control system including an inflow unit for admitting pressurized air into a cabin, an outflow unit including a motor for operating a valve to discharge air from the cabin at a predetermined rate based on an motor control signal that sets the motor speed, a control unit, and ... ### FreshPatents.com Support |
