Aerospace Ground Equipment Criteria for a Propellant Transfer Unit

1999-01-01
CURRENT
AIR1129
The primary purpose of a Propellant Transfer Unit (PTU) is to temperature-condition and weigh a specific amount of propellant, and transfer if to a vehicle propellant tank. A secondary purpose of a PTU may be to drain propellant from the vehicle tank and return it to the transfer unit when required. The transfer unit may also be used for flushing the vehicle fill lines and transfer unit with appropriate flushing fluids, followed with nitrogen for the purpose of drying the lines and weigh tank. The transfer unit may include provisions for helium purging of the propellant transfer tank and lines, ad supplying a blanket of helium pressure to the transfer tank. Each PTU consists of a piping system with appropriate propellant and pneumatic valves, regulators, relief valves, filters and a propellant pump. Various components such as a scrubber, bubbler, propellant cooler (heat exchanger), propellant weigh tank, weigh scale and a chiller may make up the balance of the assembly.

EXHAUST EMISSION LIMITS FOR DIESEL ENGINES USED IN AIRCRAFT GROUND SUPPORT EQUIPMENT AT AIRPORT ENVIRONMENTS

2002-12-16
CURRENT
AIR1312
This Aerospace Information Report (AIR) outlines the conditions which diesel engines should meet when installed and used as prime movers for aircraft ground support equipment at commercial airports. All aircraft ground support equipment with a heavy duty diesel engine as defined on page 24293 of the November 15, 1972 Federal Register and used as a prime mover for the vehicle or equipment should meet all requirements as outlined herein. Typical equipment includes fuel trucks, commissary trucks, baggage tractors, ground power units, air start units, etc.

Aircraft Ground Air Conditioning Service Connection

2012-12-05
CURRENT
AS4262B
This SAE Aerospace Standard (AS) defines interface configurations for the ground air conditioning service connection on commercial transport aircraft. In addition, it defines the clearances required to accommodate the connection of ground air conditioning hose couplings. Two types of service connections are included. The Type A connection (Figure 1) is a slotted ring with integral locking pads and is comparable to the MS33562 connection. The Type B connection (Figure 2) is a flanged tube with external locking lugs (Figure 3). The Type B connection has the same interface dimensional requirements as the Type A connection.
