Abstract: A gas turbine engine has a low speed input shaft drives a first plurality of accessories. A high speed input shaft drives a second plurality of accessories. The first plurality of accessories rotating about a first set of rotational axes perpendicular to a first plane. The second plurality of accessories rotating about a second set rotational axes perpendicular to a second plane. The first and second planes extending in opposed directions away from a drive input axis. Compressed air is tapped and passes through a heat exchanger, then to a boost compressor, and then to at least one rotatable components in a main compressor section and a main turbine section. The boost compressor driven on a boost axis, which is non-parallel to the first set of rotational axes and the second set of rotational axes.

Abstract: A gearbox for a gas turbine engine may comprise a first gear housing. A second gear housing may be located proximate a first end of the first gear housing and may extend axially from the first gear housing. A third gear housing may be located proximate a second end of the first gear housing and may extend axially from the first gear housing. A fourth gear housing may extend circumferentially between second gear housing and the third gear housing.

Abstract: An exemplary gas turbine engine assembly includes a transmission coupling a starter generator assembly to a first set of gears. The transmission is transitionable between a first mode where the starter generator assembly is driven at a first speed relative to the second towershaft, and a second mode where the starter generator assembly is driven at a different, second speed relative to the second towershaft.

Abstract: A fluid tank system comprises a fluid container that includes a sensor opening in a fluid container wall defined by a rim, and a fluid level sensor comprising a radial flange on a proximate end of a longitudinally extending electronics stem that includes a distal end. The distal end of the electronic stem is inserted into the fluid container via the sensor opening and the radial flange seats on the rim. The distal end of the electronics stem is guided via a first radial support and a second radial support to a seat that is located coaxial with the sensor opening, where the first and second radial supports are longitudinally separated and radially spaced apart to allow the electronics stem to longitudinally pass between the first and second radial supports until the flange seats on the rim ensuring that the distal end of the electronic stem is longitudinally positioned adjacent to the seat.

Abstract: An exemplary gas turbine engine assembly includes a first spool having a first turbine operatively mounted to a first turbine shaft, and a second spool having a second turbine operatively mounted to a second turbine shaft. The first and second turbines are mounted for rotation about a common rotational axis within an engine static structure. The first and second turbine shafts are coaxial with one another. First and second towershafts are respectively coupled to the first and second turbine shafts. An accessory drive gearbox has a set of gears. A compressor is driven by the first towershaft. The engine assembly further includes a starter generator assembly, and a transmission coupling the starter generator assembly to the first set of gears. The transmission is transitionable between a first mode where the starter generator assembly is driven at a first speed relative to the second towershaft, and a second mode where the starter generator assembly is driven at a different, second speed relative to the second towershaft.

Abstract: A gas turbine engine comprises a low speed spool and a high speed spool, with each of the spools including a turbine to drive a respective one of the spools. The high speed spool rotates at a higher speed than the low speed spool. A high speed power takeoff is driven to rotate by the high speed spool, and a low speed power takeoff is driven to rotate by the low speed spool. The high speed power takeoff drives a starter generator and a permanent magnet alternator. The low speed power takeoff drives a variable frequency generator.
