Second Boeing X50A Dragonfly Canard Rotor And Wing Prototypes Completes Hover Flight


Chicago IL (SPX) Dec 07, 2005
Boeing's second canard rotor/wing (CRW) technology demonstrator the X-50A Dragonfly unmanned air vehicle has successfully completed a four-minute hover flight at the U.S. Army's Yuma Proving Ground in southwest Arizona. The aircraft reached an altitude of about 20 feet above ground.

"Our first flight test objectives were met today," said Clark Mitchell, Boeing Phantom Works program manager for the CRW prototype. "This is a significant achievement toward validating the new stopped-rotor technology."

Under joint development by Boeing Phantom Works and the Defense Advanced Research Projects Agency (DARPA), the CRW is a revolutionary aircraft that combines the speed and range of fixed-wing flight with the flexibility of rotary-wing flight. It also incorporates tip jet propulsion and stopped rotor technologies.

"The most significant objective met was verification that software compensation effectively reduces the rotor control issue we were having, or cross coupling," he said. The phenomenon of cross coupling was a finding in the mishap investigation of Ship 1 in 2004 that led to wind tunnel tests for Ship 2 at the Boeing helicopter facility in Philadelphia earlier this year.

Ship 2 then completed ground checkout testing at the Boeing facility in Mesa, Ariz., where it was configured for flight. After a flight readiness review, the vehicle was shipped to Yuma where it completed a preparatory "pop up" flight Nov. 4. The flight lasted only about 30 seconds during which the aircraft stabilized briefly at 16 feet above the ground and then landed. Success with the initial flight led to the hover flight Dec. 2.

Mitchell said that flight tests are expected to continue into early next year. The flight-test schedule calls for 11 flights. Under the remote control of a pilot in a ground station cockpit, the X-50A Dragonfly will gradually perform more extensive hover flights, then forward-moving rotary wing flights.

The test program will culminate with the first ever "conversion" from rotary wing flight to fixed-wing flight and back again to rotary wing flight for landing. The conversion requires the main rotor to stop turning in flight, and lock in place to become a fixed wing for high speed flight.

Ship 1, the first Dragonfly prototype vehicle, was involved in a flight mishap on March 23, 2004, that led to a joint investigation by Boeing and DARPA. The findings identified cross coupling of the rotor controls as the main cause of the mishap. Since then, improvements have been incorporated into Ship 2 that address design issues related to findings. These include changes such as new rotor torsion springs for increased control power, new flight control software and a flight data recorder.
