Abstract: An air conditioning system (10) provides a pack conditioned air passage (22) which intersects with a recirculation passage (28) prior to communication of the combined air flow with a mixer (30). The combined air flow traverses a distance(A-B) between the intersection between the pack conditioned air passage and the recirculation passage (A) and an entry (B) to the mixer which reduces the required volume of the mixer as compared to conventional systems.

Abstract: Prior variable speed constant frequency (VSCF) generating systems which utilize an inverter to derive constant frequency power from variable frequency power developed by a generator driven by a prime mover have excitation of the generator. Such a control technique, however, does not provide voltage regulation of individual phases and minimize undesirable distortion in the system output. In order to overcome the foregoing problem, a control (30) for a VSCF system (10) having a generator (12) and an inverter (22) which receives DC power from a rectifier (16) coupled to the generator (12) controls switches in the inverter (22) to maintain a parameter of the AC power developed by the inverter (22) at a desired level and controls the power applied to an exciter (33) of the generator (12) to maintain a parameter of the DC power at a particular level relative to the parameter of the AC power developed thereby. Distortion in the inverter output is thereby minimized.

Abstract: Prior generating systems utilizing electrically-compensated constant speed drives (ECCSD) have typically required a separate starter motor for starting a prime mover which supplies motive power to the ECCSD, thereby increasing the size and weight of the system. In order to overcome this problem, a generating system is provided with circuitry coupled to the electrical power windings of a permanent magnet machine (PMM) forming a part of the ECCSD for causing the PMM to develop motive power which causes an output shaft of a differential of the ECCSD to rotate at increasing speeds. When the output shaft of the differential reaches a predetermined speed, a generator (12) coupled to the output shaft of the differential is supplied external or ground power which in turn causes the generator (12) to operate as a motor and return motive power (16) through the differential to the prime mover to start same and bring it up to operating speed.

Abstract: An on-board inert gas generating system (10) includes a flow control valve (28) modulated according to changes in ambient conditions to minimize changes to oxygen content within a fuel tank (18). The quality of the nitrogen-enriched air stream (16) that is provided by the air separation module (12) varies in response to flow. Higher flow rates through the air separation module (12) removes less oxygen relative to lower flow rates. The amount of flow through the air separation module that produces the least amount of oxygen within the fuel tank (18) is determined for an ambient pressure (46) and provided by modulating the flow control valve (28).

Abstract: A system for controlling an electric motor includes a controller and a position indicator that provides position information regarding at least one motor component to the controller. The controller utilizes phase relationships indicative of the position information to determine the actual position of the component of interest. The phase information in one example is derived from the output of a resolver that provides two output signals corresponding to sin (theta) and cos (theta), where theta is the angular position. Utilizing the phase relationship simplifies the task of determining accurate position information that is useful to modify motor control signals to compensate for latency when making position determinations, velocity calculations or both. The inventive system makes it possible to use less expensive electronics to arrive at more reliable results.

Abstract: A method of linearizing the output performance of a switched reluctance generator comprises the steps of exciting the switched reluctance generator during a first phase of operation at a turn-on angle which needs not be accurately calculated to produce the desired excitation current. Next, during a second phase of commutation, the switched reluctance generator is freewheeled when a phase current of the switched reluctance generator exceeds a first calculated current level. This freewheeling continues until the phase current of the switched reluctance generator exceeds a second calculated current level, at which point the switched reluctance generator enters the generation phase of its commutation cycle. The linearization of the performance occurs because the first and second calculated current levels are calculated as a function of energy converted per electrical cycle. This function of energy converted per electrical cycle is calculated using an inductance of the switched reluctance generator in an aligned position and an inductance of the switched reluctance generator in an unaligned position. The shape of a graph of the flux linkage versus the phase current is controlled through the selection of the first and second calculated current levels which increases efficiency while linearizing the performance of the switched reluctance generator. The area enclosed by this graph is equal to the energy converted per electrical cycle.
