Finally, the aircraft became the first vehicle in the convertiplane series as the XV-1.

Working the controls as the convertiplane whirled like a dervish, he somehow managed to keep fight side up.

Around 1843, he was the first to suggest the idea for a convertiplane, an idea which was published in a paper written that same year.

From the way the convertiplane had gone down, the sol- dier felt chances were good that Grimaldi was still alive.

The Convertiplano is a cancelled Brazilian convertiplane project.

The convertiplane shuddered like someone stricken with palsy when the antiaircraft shell took it in the tail section.

Gfimaldi stumbled toward the back of the convertiplane and found the side door had buckled from the impact and was ajar.

On impact, the prop shat- tered into deadly shards that pierced the convertiplane's body and Plexiglas windows.

Ultimately, it was determined that the XV-1's convertiplane configuration was too complex for the small advantages gained over conventional helicopters.

The convertiplane featured a single Continental-built R-975 radial piston engine that powered twin air compressors.

Spreading flames further lit up the area, consuming brush and foliage now, as well as fuel and com- bustibles from the convertiplane.

A convertiplane is an aircraft that converts in flight to change the method to obtain lift, and is capable of vertical take-off and landing.

Sikorsky S-57/XV-2: Supersonic convertiplane with single blade retractable rotor.

The original military designation was XH-33, classifying it as a helicopter, but its designation was changed to XV-3 in the convertiplane series.

The USMC military markings had been removed, and the whole convertiplane had been repainted a flat black to blend in with the night.

In the 1950s it built some ultra-light helicopters the RH-1 to test some rotor features and its last design the K-25 was an experimental convertiplane using tilt-rotors.

First flight of Kaman's experimental Convertiplane equipped with a GE J-85 engine and wings from a Beechcraft Queen Air.

With Hawkins and Encizo seated almost comfortably be- hind him, Bolan brought the notebook computer out of his chest pack and set it up, plugging into one of the power supplies provided in the convertiplane.

Henrich Focke revived the design in the early 1950s on behalf of Brazil's Centro Técnico Aeroespacial (CTA), at the time the air force's technical center, who had contracted him to develop a convertiplane.

The Bell XV-3 (Bell 200) was a tiltrotor aircraft developed by Bell Helicopter for a joint research program between the United States Air Force and the United States Army, to explore convertiplane technologies.

The Sikorsky XV-2, also known by the Sikorsky Aircraft model number S-57, was a planned experimental stoppable rotor aircraft, designated as a convertiplane, developed for a joint research program between the United States Air Force and the United States Army.
