摘要： Disclosed is a throttle quadrant arrangement utilizing a throttle lever mechanically connected to three Rotary Variable Differential Transformers (RVDTs). The signals from the RVDTs are monitored by a process where the processing component. More specifically, RVDT outputs are monitored by the engine control system to determine if they are outside a predetermined range of operability. If an RVDT is not operable, the engine control system establishes a thrust output using the signal from one of the functional two. If only one or none are within the range, the system moves on to a default mode.

摘要： An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.

摘要： A system is provided for interfacing a Full Authority Digital Engine Control (FADEC) system with engine sensors and actuators using miniaturized Low Temperature Co-fired Ceramic (LTCC) substrates operating as smart notes that communicate digitally over a data bus to a miniaturized LTCC operating as a data concentrator. The use of smart nodes and/or data concentrators assembled on LTCC substrates provides enhanced thermal and vibration performance along with resistance to hydration, improved reliability and reduced overall size of the circuitry unit.

摘要： Disclosed is a throttle quadrant arrangement having a throttle lever which is independently mechanically connected to different Rotary Variable Differential Transformers (RVDTs). A friction lever selectively creates and releases friction from the throttle lever to enable it to be selectively positioned. The system is configured such that the mechanical connections existing between the throttle lever and the RVDTs are shielded from the friction created by the friction lever.

摘要： A system for reducing rotor acoustics of an aircraft. The system includes a structural feature of an aircraft and a propulsor configured for fixed-wing flight mounted on the structural feature. The system further includes a plurality of rotors mounted on the structural feature. The plurality of rotors are configured to include a first rotor, a first motor mechanically coupled to the first rotor, a second rotor, and a second motor mechanically coupled to the second rotor. The system further includes an aircraft controller communicating with the first motor, second motor, and the propulsor. The system includes an alignment module configured to place the second rotor in alignment with the first rotor. The system further includes a rotational control module configured to initiate rotation of the plurality of rotors. Initiating rotation of the plurality of rotors further includes initiating rotation of the first rotor and the second rotor.
