Vulcan XH558 Wash System

Rochem is proud to be an active supporter of the Vulcan To The Sky Appeal

Rochem Technical Services are proud to announce their support of the Vulcan to the Sky Appeal Trust. We are supporting the continued operation of the Vulcan with a new engine Compressor Wash System that has been designed & manufactured in our factory in Winchester, Hampshire.

This new wash system will help to keep the four Rolls Royce Olympus jet engines of this last ever flying Vulcan corrosion free, clean and efficient throughout its annual air show programme and in turn also help to extend the service life of major engine components.

Since the Vulcan flies mainly at relatively low heights during its air show sorties its engines can ingest airborne salts and other contaminants, some of which can settle on the compressor blades of the engines so it is important to have a simple and efficient compressor wash system that can be used to thoroughly clean the engines on a regular basis between air shows and during maintenance periods.

Rochem Technical Services has been a world leader for over 30 years in the design and supply of gas turbine and jet engine cleaning systems and chemicals and was delighted to assist the Vulcan team when asked to design and supply a new compressor wash system for this remarkable aircraft.

The most essential component of the new wash system is an atomising header which delivers pure water and/or a special Rolls Royce approved Rochem cleaning solution in highly atomised form into the intake of the Olympus jet engines when they are being turned on their starter motors.

The entire water washing and/or chemical cleaning process takes just two minutes but the wash procedure can be repeated a number of times if needed to ensure that the engine compressors – which are the heart of any jet engine or gas turbine – are spotlessly clean and efficient before each air show sortie.

Rochem is providing the entire wash system – including water and chemical solution tanks and the portable wash pump skid – at its cost to the Vulcan team together with ongoing supplies of cleaning chemical and technical support during the remaining operating life of this famous aircraft; and long may she fly with the continued generous support of the public who continue to be thrilled by her air show demonstration flights all over the country.
