Canada-headquartered company GasTOPS has achieved an engine sensor delivery milestone for the F-35 Lightning II joint strike fighter programme.

The company delivered its 3,500th engine sensor for the aircraft.

The F-35 Lightning II is a Lockheed Martin-built fifth-generation multirole stealth fighter jet.

It is developed in three variants F-35A, B and C for the US Air Force (USAF), US Navy and US Marine Corps and programme partners from Nato and other US allies.

All these three variants are powered by the Pratt and Whitney low-bypass augmented turbofan F-135 engine, a derivative of the F119 fitted on the F-22.

Despite the impact of the Covid-19 pandemic, demand for the F-35 programme remains steady and Gastops’ production facility continued to meet all scheduled deliveries.

Gastops said that its MetalSCAN Oil Debris Monitoring sensors are leading among the company’s sensing technologies.

The MetalSCAN sensing technology provides ‘a real-time condition indication of the health of critical components in the engine’. It is fully integrated into the F-35’s F135 engine’s lubrication system on all three variants, and on the LiftFan drive gearbox for the F-35B version.

Gastops noted that it has been a part of almost every major Pratt & Whitney engine programme.

The company’s MetalSCAN technology is also used to monitor key components for the Pratt & Whitney GTF commercial engine family.
