Gulfstream G500 completes 430 hours of flutter testing

Gulfstream Aerospace Corp. said the Gulfstream G500 has completed flutter testing, achieving another milestone in the new aircraft´s flight-test program.

The first G500 test aircraft, T1, performed the tests over the course of more than 50 flights.

As T1 performed flutter testing, the second test article, T2, finished climatic chamber testing at the McKinley Climatic Laboratory, Eglin Air Force Base, Florida. The aircraft endured three days of hot testing, with temperatures reaching 131 degrees Fahrenheit/55 degrees Celsius, followed by two days of cold testing, with temperatures as low as -40 degrees F/-40 degrees C.

Since T1 took its first flight on May 18, 2015, the aircraft has surpassed more than 320 flight hours. It has reached a maximum speed of Mach 0.999 and a maximum altitude of 53,000 feet/16,154 meters. T1´s longest flight to date lasted more than five hours. Additional test activities are continuing on track, including envelope expansion, air data system testing, aero performance, brakes and field performance, handling qualities and flight controls.

The second and third G500 flight-test aircraft, T2 and T3, both took their first flights on Nov. 20, 2015. In addition to the climatic chamber testing, T2 is focusing on flight loads validation, along with aircraft performance and systems testing.

T3 is the primary test bed for the all-new Symmetry Flight Deckâ„¢. T3 will also be used to evaluate ice-protection system performance, landing gear and nosewheel steering operation, environmental control system performance and the cabin pressure control system, as well as community noise testing. T3´s longest flight to date lasted more than six hours.
