This specification covers the requirements for aircraft, hydraulic, self-sealing, quick disconnect couplings, for use in Type II hydraulic systems (-65 to +275 °F temperature range) as defined by MIL-H-5440.
The purpose of this section is to provide methods and a set of convenient working charts to estimate penalty values in terms of take-off fuel weight for any given airplane mission. The curves are for a range of specific fuel consumption (SFC) and lift/drag ratio (L/D) compatible with the jet engines and supersonic aircraft currently being developed. A typical example showing use of the charts for an air conditioning system is given. Evaluation of the penalty imposed on aircraft performance characteristics by the installation of an air conditioning system is important for two reasons: 1 It provides a common denominator for comparing systems in the preliminary design stage, thus aiding in the choice of system to be used. 2 It aids in pinpointing portions of existing systems where design improvements can be most readily achieved.
This section presents methods and examples of computing the steady-state heating and cooling loads of aircraft compartments. In a steady-state process the flows of heat throughout the system are stabilized and thus do not change with time. In an aircraft compartment, several elements compose the steady-state air conditioning load.
This specification covers the requirements for solid-state frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz input and 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704D quality power. The frequency converter shall be a self-contained unit suitable for the environment of intended use. Typical applications include dedicated use at passenger loading bridges (mounted under the bridge in telescoping bridge applications or fixed installation at base of stationary type loading bridges) with weatherproof enclosures or hangar/lab use where indoor fixed or portable units can be used.
This Aerospace Recommended Practice (ARP) provides criteria for design and location of power supplies, controls, light fixtures, and associated equipment which are used to provide emergency illumination in transport aircraft, designed to FAR 25 (Ref. 1) for operation under FAR 91 and FAR 121 (Ref. 2), and also in compliance with FAA Advisory Circular AC25.812-1A (Ref. 3). It is not the purpose of an ARP to specify design methods to be followed in the accomplishment of the stated objectives.
This SAE Aerospace Information Report (AIR) covers the general requirements for and the listing of manufacturers identification that appear on electrical/electronic wiring devices and accessories as required by individual product specifications.
This standard sets the basic requirements for a VOR receiver, whose function is to receive and process VOR signals in the frequency band 108.00 to 117.95 MHz. Provides traditional analog outputs and a digital output of omni bearing.
This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings, or heading procured in SI (metric) units. AMS 5706 is the inch/pound version of this MAM. These products have been used typically for parts, such as fasteners, flanges, and rings, requiring high strength up to 815 degrees C and oxidation resistance up to 955 degrees C, particularly those parts which are formed or welded and then heat treated to develop required properties, but usage is not limited to such applications.
This specification covers a nickel alloy in the form of wire, rod, strip, foil, and powder and a viscous mixture (paste) of the powder in a suitable binder and procured in metric units. AMS 4778 is the inch/pound version of this MAM. This filler metal has been used typically for joining corrosion and heat resistant steels and alloys requiring corrosion and oxidation resistant joints with good strength at elevated temperatures, but usage is not limited to such applications. Also may be used as a corrosion and oxidation resistant hard coating.
This section presents the basic equations for computing ice protection requirements for nontransparent and transparent surfaces and for fog and frost protection of windshields. Simplified graphical presentations suitable for preliminary design, and a description of various types of ice, fog, frost, and rain protection systems are also presented.
