ATR is a standard that specifies the form and function of the "black box" installed on the aircraft. This standard is also known as ARINC and designated as ARINC404 standard.
ARINC404 specifies the mechanical dimensions of line replaceable units (LRUs) and their shelving systems at different locations on an aircraft. LRUs are installed on specially designed trays and offer mechanical fixtures, shock absorption options, cooling facility options, and plug-in functionality options.
Atr is increasingly being deployed on wheeled and tracked vehicles and used for onboard applications. Each application is affected by a series of harsh environmental factors, including shock, vibration, temperature, humidity, and salt, all of which need to be considered. ATR has been introduced into unprecedented applications, including surveillance, data collection, storage, and weapon control.
The convection and conduction cooling ATR (Air Transport Rack) shell provides a standardized and cost-effective solution for applications based on PCI, VME, VME64x, VXS, cPCI, and VPX. According to the 1/2, 3/4, 1, and 1 1/2 high, high, and short formats of ARINC404A, ARINC600, and IEEE1101.10 specifications, the modular design concept allows for a wide range of customization options without the cost and lead time losses associated with custom design.
All aluminum Atr is made of perforated and formed metal plates and grinding plates or brazed aluminum. A movable front panel allows I/O customization to meet precise application requirements and increased configurability.
The ATR casing uses electrostatic dust filters, honeycomb EMI filters, and narrow screw spacing to seal each external seam to ensure compliance with MIL-STD-461 standards. The sturdy and durable design meets the requirements of MIL-STD-810, MIL-STD-167, and MIL-STD-901D for impact, vibration, and structural integrity.
