Helicopter cleaning

A helicopter essentially consists of 4 sections which are completely maintained / repaired, also separately, every 250 flying hours:

the hydraulic system
the mechanical system
the electronic system
The fuselage

Authorized methods up to now: cold water as well as 2 approved alkaline cleaning agents – cleaning by hand (larger surfaces partially with steam cleaner with cold water).

The hydraulic system: soiled with oils, greases and sand. Very complex placements with many lines and heavily accessible.
The mechanical system: soiled with oils and sand
The electronic system: here was only cleaned in the area of the wires
The fuselage: soiled with everything that can hit on a helicopter. Cleaning with a temperature of 65° C.

Short declaration: The cleaned helicopters are 40 year old transport helicopters.
L=18m H=4m B=4m (without rotor)
At the moment there still exist 23 pieces. All of them are used in Afghanistan (flight there and back in a Tupolev).

Result

Considerably faster than the conventional hand cleaning and far more efficient. Actual status approx. 10 working days with 4 persons and with our technology (2 devices) less than 1 week.
