LORD Corporation Completes Design Review for LearJet 85 Aircraft Engine Isolation System

The isolation system for the Learjet 85 aircraft builds on proven concepts from previous LORD/P&WC efforts while also introducing new innovations.


(Cary, NC – June 6, 2011) -- LORD Corporation – a leader in the management of vibration, motion and noise control – has completed the critical design review for engine isolators for Bombardier’s Learjet 85* aircraft.

OEM Pratt & Whitney Canada Corp. (P&WC) has tasked LORD with the design, analysis, qualification and production of forward and aft elastomeric engine isolators. Delivery of the first production parts are expected later this year.

The first clean sheet Learjet aircraft design in over a decade, the Learjet 85 aircraft combines both new and proven technologies, and LORD Corporation’s design continues that theme. The isolation system for the Learjet 85 aircraft builds on proven concepts from previous LORD/P&WC efforts while also introducing new innovations. For example, the Learjet 85 aircraft design includes the use of new elastomeric materials that provide a higher resistance to drift, which increases the longevity of the isolators.

According to John Smid, Managing Fixed Wing Engineering and Product Development, LORD Corporation, the design and production of the mounting system, as well as the resulting low-weight isolators, make for a unique solution.

“LORD has a long history of proven solutions working with P&WC,” said Smid. “An integrated approach in designing an engine isolation system pays dividends in terms of total system performance and weight, as well as meeting noise requirements.”

According to Matthew McGill, LORD Product Engineer, the design team embraced challenging goals for technical and cost improvements versus existing designs. The solution features light-weight titanium forward isolators, as well as a fire-proof aft isolator that is attached to the outer bypass duct of the engine.
