Flight Testing
Following wind tunnel and flight testing by Bell, the aircraft was then moved to NASA Dryden, which is at Edwards AFB in the California High Desert. The XV-15 flight testing continued expanding its flight envelope. It was able to successfully operate in both helicopter and normal aircraft flight modes and smoothly transition between the two. Once the aircraft was considered sufficiently tested, it was returned to Ames for further testing.
The XV-15s were sufficiently tested by 1981 that one of the aircraft was taken to that year's Paris Air Show for demonstration flights.
The XV-15s were a standard demonstration in the annual summer airshow at the co-located Moffett Field Naval Air Station for a number of years in the 1980s. Both XV-15s were flown actively throughout the 1980s testing aerodynamics and tiltrotor applications for civilian and military aircraft types that might follow, including the V-22 program.

Famous quotes containing the words flight and/or testing:
“No Raven’s wing can stretch the flight so far
As the torn bandrols of Napoleon’s war.
Choose then your climate, fix your best abode,
He’ll make you deserts and he’ll bring you blood.
How could you fear a dearth? have not mankind,
Tho slain by millions, millions left behind?
Has not conscription still the power to weild
Her annual faulchion o’er the human field?
A faithful harvester!”
—Joel Barlow (1754–1812)
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
