The Nexcelle joint venture’s engine nacelle is installed on Bombardier’s no. 1 Global 7000 business jet
October 12, 2015
The first two engines with nacelles from the Nexcelle joint venture of Safran and GE Aviation have been installed on Bombardier's no. 1 Global 7000 business jet, marking another milestone in Nexcelle's development of integrated propulsion systems.
These GE Aviation Passport engines with their Nexcelle nacelles were processed at the GE Aviation Peebles Test Operation in Peebles, Ohio, enabling the integration stage – including fit and functional checks – to be performed on the complete Passport Integrated Propulsion System (IPS).
The two-engine/nacelle shipset was transported to Bombardier's Toronto production site, where installation was completed on the first Global 7000 Flight Test Vehicle (FTV1).
Integration of the two engines at Peebles followed earlier testing with the Passport IPS, including more than 100 flight hours with another engine installed on GE Aviation's Boeing 747 testbed aircraft, operated from Mojave, California.
Nexcelle was created in 2008 by the Safran group's Aircelle and GE Aviation's Middle River Aircraft Systems. Nexcelle and its parent companies work together in evolving truly integrated propulsion systems, with the goal of making them more operationally efficient, cost-effective and aerodynamically optimized.
For the Passport Integrated Propulsion System on Bombardier's Global 7000, the Nexcelle joint venture is a key partner to GE Aviation – supplying the nacelle elements that are composed of the inlet, fan cowl, the thrust reverser and its hydraulic actuation system.
Among the key features of Nexcelle's nacelle system for the Passport IPS are an innovative anti-ice system that uses a directed flow nozzle concept; and a 360-degree, single-piece extended composite inner barrel incorporating advanced acoustic protection for lower engine noise levels.
Also, the simplified clamshell type-composite fan cowl developed for the nacelle allows for improved maintenance, while a target-type thrust reverser with kicker plates and a fixed nozzle provides consistent cruise performance and enhanced thrust efficiency in reverse mode. Overall, the nacelle designed for Passport will be lighter than the state-of-the-art nacelles of its class, thus contributing to powerplant performance.
