Special Aircraft Equipment

aero-contact has been developing aircraft equipment for 20 years now.

A mile stone was the internal water tank system for the Mi-14 fire fighter helicopters. But we are not limited to developments in the aviation sector only. There is a wide range from Aviation to Mining Industry and Fire Fighting where our products are used.

On customers request aero-contact manufactures various equipment based on customers need and data.

The scope of special equipment is wide spread, from a single airplane tow bar to a medium or high performance hydraulic ground power unit. We also loan our 28 V DC hydraulic gpu to our European customers.

Nitrogen boost cart

Dirty…but serviable. Used on the MiG-29 inert gas system (fire protection of fuel tanks).  Increases nitrogen bottle pressure up to 400 bar.

Can be also used to recharge half empty bottles. Makes out of 2 or 3 half empty bottles a full one.

the engine preservation rig serves the TV2-117 and TV3-117 engines of the Mil helicopter series, as well the L-39 engine AI-25TL
