1.1Background。b - 2轰炸机项目办公室已经确认了need for portable hangars to support deployed operations. These hangars must be robust in construction to provide reliable protection for the aircraft and safety for the maintenance crew. They must also maintain stringent inside temperature and relative humidity conditions during B-2 aircraft maintenance operations. This System Performance Specification defines the Extra Large Deployable Aircraft Hangar System (XLDAHS). The objective of the specification is to outline the performance and physical characteristic requirements for a system that meets established physical and functional requirements for a B-2 aircraft maintenance hangar over a wide range of environmental conditions.

1.2Mission。可部署可部署的避难所是支持（1）对重大地区冲突的回应所需的运营能力，（2）和平执法和干预行动，（3）为冲突做准备，（4）海外存在，（5）准备和可持续性，（5）（6）移动性和预位。许多国家最近不愿允许在其土壤上建立外国军事基地。为了应对这种情况，并在“全球范围...全球权力”的学说下，美国空军准备在全球部署。在此任务范围内，必须快速运输，竖立和重组XLDAH，因此，对可以在全球范围内空运的轻质，低包装系统的要求。

The 463L system encompasses all phases of cargo loading, including material-handling equipment, cargo-loading platforms, restraint equipment, and in-aircraft systems. The 463L system is the USAF standard for moving concentrated cargo to be air landed. It comprises the following major components:

�Dual-rail系统。dual-rail系统安装ed in all airlift or 463L-capable military aircraft. This system consists of rows of rollers that allow the palletized cargo to easily move into the aircraft. Many of these rollers are stowable to convert the cargo deck to a flat, clear loading surface for wheeled or tracked cargo. The side rails guide the pallets into the aircraft and provide lateral and vertical restraint. These rails are equipped with detent locks that hold the pallet securely in place once inside the aircraft. The locks also prevent the forward and aft movement of pallets during flight. Cargo compartment floors also contain a series of tie-down fittings for securing wheeled or tracked cargo with chains.

�463 l托盘。463 l托盘是由腐蚀-resistant aluminum with a soft wood core and is framed on all sides by aluminum rails. The rails have 22 attached tie-down rings with six rings on each long side and five rings on each short side. Each ring has a 7,500-pound restraint capacity. The rails also have indents (notches) which are designed to accept the detent locks located on numerous types of material-handling equipment on all airlift-capable aircraft. The overall dimensions of the 463L pallet are 88 inches long by 108 inches wide by 2-1/4 inches thick. The usable dimensions of the surface area are 84 inches wide by 104 inches long. This allows two inches around the periphery of the pallet to attach straps, nets, or other restraint devices. An empty pallet weighs 290 pounds (355 pounds with nets) and has a maximum load capacity of 10,000 pounds. Two or more pallets can be connected together for movement of cargo that exceeds the dimensions or weight limitations of a single pallet.

�463L pallet nets. There are three nets to a set: one top net (yellow) and two side nets (green). The side nets attach to the rings of the 463L pallet. The top net attaches by hooks to the rings on the side nets. The nets have multiple adjustment points and can be tightened to conform to loads of almost any shape. A complete set of 463L nets pro vides adequate restraint for a maximum of 10,000 pounds when properly attached to a 463L pallet. A complete set of nets weighs 65 pounds.

�Other restraint devices. 10,000 and 25,000 pound (capacity) chains and locking devices are available to restrain large or heavy items such as containers, vehicles or tracked equipment. 5,000 pound straps are available for individual item restraint or to supplement 463L nets.

�Specialized 463L compatible containers with their own base or which incorporate an integral pallet base are available.

�Wheeled vehicles may be loaded directly on the cargo compartment floor and restrained with 10,000 and/or 25,000 pound capacity chains.
