An aircraft penetrating nozzle comprises a penetrator which has a harden tip. The penetrator functions to open a passageway in a barrier or skin of an aircraft to permit the aircraft penetrating nozzle to pass thereinto. The penetrator is securely attached to a frustum which comprises a plurality of nozzles which disperse fire extinguishing fluids interior to the aircraft perpendicular to the longitudinal axis of the aircraft penetrating nozzle and forward of the perpendicular. The frustum is se...

The present invention relates to an aircraft transparency including an electroconductive metal oxide coating over a rigid plastic substrate, and a polyurethane protective liner over the metal oxide coating, and more specifically to the use of a primer for adhering the metal oxide coating to the substrate and/or a primer for adhering the polyurethane protective liner to the metal oxide coating. The metal oxide primer includes a carbonate diol-based crosslinked polyurethane. The polyurethane prime...

An aircraft loader having bridge and main elevators is provided with pivotally mounted trays at the rearward end of the bridge elevator. The trays serve as transit means for the passage of load units between the two elevators both when the two elevators are level and when they are out of level to a degree. The trays function also as part of a level control system whereby the levels of the main elevator and trays tend to be adjusted to match the level of the bridge elevator.

A toy aircraft having a fuselage split into two halves which carry wings and are hinged together for movement from a launching position where a hook on one half projects for launching purposes, to a flight position where the hook blends into the other parts of the aircraft.

An aircraft carrier, the main deck of which is provided with an armored enclosure housing at least one work area for servicing aircraft. Service bays are arranged sequentially in the work area within the hangar in assembly-line fashion. Takeoff assisting means for the aircraft is provided on a portion of the main deck. The work areas can be divided by fire and explosion resistant doors which open and close with each refurbishing phase started or completed, with major increase in the speed of squ...

An aircraft seat having a pivotal seat back which has an upright position for occupancy and an advanced position for affording additional living space to the passenger occupying the next rearward seat including a detent mechanism to maintain the seat back in either of its positions and to allow passenger adjustment of the seat back between these two positions.

A lead-acid aircraft battery having a unique arrangement for making connections to the battery. The arrangement includes L-shaped members on the upper surface of the casing having cylindrical apertures extending horizontally therethrough. Threaded pin terminals insert through a receptacle assembly positioned to a side wall of the battery housing and are fastened by nuts to the L-shaped members. The pin terminals have axially-aligned surfaces for engaging a tightening tool so that assembly time i...

An aircraft cabin is climatized by tapping air from the engine compressors and feeding it into the cabin through a loop which includes a compressor, a cooling turbine driving the compressor, and several cooling stages. A second loop, using preferably helium, includes a second compressor and a second turbine, the second compressor being driven by both turbines, and the cooled helium is in heat exchange with another cooling loop which runs through instrument compartments. Discharged cabin air is u...

A toy aircraft having a rotatable wing assembly having at least two blades of aerofoil cross-section extending radially outwardly from the axis of rotation of the assembly, each blade having a zero pitch angle so that in operation the blades have a negative pitch angle relative to the airstream.

A combined vertical speed and windshear indicator instrument for an aircraft has a graduated dial (2) and a conventionally driven pointer (3) for indicating the vertical speed. In addition the instrument has an independent pointer (4) which is driven so that it indicates, to the same scale as the vertical speed, the rate of change of total energy of the aircraft (energy rate) according to the formula dh/dt+(V/g)(dV/dt) where h is the height of the aircraft and V is its true air speed. Under stab...
