The Barrier To Aero-Engine Performance

Permeability - the Barrier To Aero-Engine Performance

Amongst the most safety-critical barriers to Aerospace performance is the complex task of preventing hydrocarbons and water seeping into the wrong parts of the engines and structure.   Not only can this be dangerous but it can seriously affect the electronics, navigation or power systems in an aircraft, missile or drone.

Unfortunately both water and hydrocarbon vapour will permeate through just about any material, seal or fabric, sometimes in large volumes and especially in zones of high temperatures and pressure. There are many well documented examples where this has caused missiles and craft failure – sometimes with catastrophic results.  
Conventional tests on materials, tanks, pipes, seals and components are laboriously slow and expensive, taking days, weeks or even months - and even then they are often neither accurate nor consistent.  To overcome this, Versaperm has produced an upgraded version of its vapour permeability measurement system, with a new sensor range, that allows measurement under a range of temperatures and pressures.
The system is simple to use, fast and precise, and requires, at most, minimal training to use.  It also requires little or, (usually), no re-calibration. Some results can be produced in as little as 30 minutes and accuracy is in the Parts Per Million (PPM) range for most commonly used materials and gases (PPB in some cases).
Versaperm’s new system can optionally be configured to measure permeability for a variety of gases including hydrocarbons, solvents, oxygen, carbon dioxide, helium and water vapour.  The equipment highly automated.

Versaperm also offers a laboratory testing service and technical consultancy for companies that test too few samples to make the purchase of equipment viable.
