Racking & Structures
LRUs / Boxes
Lightweight sheet metal construction, suitable for airborne electronics.
Vary in size, shape and function. Available as basic constructions, or more complex fully assembled enclosures with system electronics.
Hold Downs, Pins & Hooks
Hutchinson Stop-choc also supply a full range of ancillary equipment including; interface seals, hold down devices, insertion/extraction systems, rear location pins and bushes, plenum chambers and metering plates.
An extensive range of hold downs include torque limiting hold downs, PAN standard hold down devices and fail-safe self locking hold downs. These systems ensure equipment cannot become loose or detached due to vibration or thermal cycling. They also ensure that the correct level of torque is applied to the fixings preventing over tightening and consequential damage of the tray, equipment and hold down system.
Seals are available to suit all ARINC 404A and ARINC 600 sizes. The seal/integral metering plate may be attached either with screws and nuts or rivets. The airflow holes that are not required to be open can be closed with plastic plugs.
The seals/metering plates are carefully designed to give minimum weight and maximum efficiency by using silicone elastomers and aluminium alloy.
The seals are used as standard components on our ARINC trays and have been tested to proven life and efficiency leakage.
Over the past 50 years, Hutchinson has developed an extensive library of product designs and capabilities to support and protect sensitive equipment in harsh environments for fixed-wing and rotary aircraft.Where a standard design is not suitable, we have the ability to produce tailor made trays to be manufactured according to your requirements.
Supplied in accordance with ARINC & ATR standards we can provide lightweight aluminium avionics trays, racks & racking or complex fully qualified assemblies inclusive of connectors, cooling systems, wiring & vibration isolation systems.
Hutchinson Stop-choc also design and manufacture heavy duty isolated structures for the mounting of electronics and communication systems in military vehicles. These rugged avionics racking systems take in to account earth bonding requirements, military standard fixing arrangements and vibration and shock requirements.
Where avionics racking systems use rear electrical connectors which are not visible with the equipment installed, Hutchinson Stop-choc insertion/extraction systems allow for safe and reliable mating and un-mating of these connectors. Our mating/un-mating devices meet PAN standards and we have a full range suitable for aircraft and military equipment.
