The McDonnell XV-1 is an experimental Convertiplane developed by McDonnell Aircraft for a joint research program between the United States Air Force and the United States Army to explore technologies to develop an aircraft that could take off and land like a helicopter but fly at faster airspeeds, similar to a conventional airplane. The XV-1 would reach a speed of 200 mph (320 km/h; 170 kn), faster than any previous rotorcraft, but the program was terminated due to the tip-jet noise and complexity of the technology which gave only a modest gain in performance.

rdfs:comment	ماكدونيل إكس في-1 (بالإنجليزية: McDonnell XV-1)‏ هي طائرة تجريبية أنتجت في الولايات المتحدة. من صناعة طائرات ماكدونل. كان أول طيران لها في 14 يوليو 1954. صنع منها 2 طائرة. (ar) Die McDonnell XV-1 war ein Flugschrauber, der zum Start über einen zuschaltbaren Blattspitzenantrieb am Hauptrotor verfügte. (de) El McDonnell XV-1 fue un girodino experimental desarrollado por un programa de investigación conjunto entre la Fuerza Aérea y el Ejército estadounidenses, para explorar tecnologías que desarrollasen una aeronave que pudiera despegar y aterrizar como un helicóptero, pero volar a velocidades más altas, similar a un avión convencional. El XV-1 alcanzaría la velocidad de 320 km/h, más rápido que cualquier nave de rotores anterior, pero el programa terminó debido al ruido de los reactores de punta y a la complejidad de la tecnología, que solo le proporcionaba una modesta ventaja en prestaciones.

(en) Le McDonnell XV-1 est un aéronef expérimental américain, hybride entre avion et hélicoptère, mis au point dans le cadre d'un programme de recherche conjoint entre l'US Air Force et l'US Army, afin d'explorer les technologies permettant de développer un avion capable de décoller et d'atterrir comme un hélicoptère mais de voler à une vitesse équivalente à celle d'un avion conventionnel. (fr) XV-1 コンバーチプレーン（「転換式航空機」の意味）は、アメリカ空軍とアメリカ陸軍との共同研究計画のために開発された実験的な複合ジャイロプレーン（ホットサイクル式ローターによる、擬似的な複合ヘリコプター）である。本機もまた、回転翼を用いて垂直離着陸飛行するが、従来の回転翼機と比較して、より高速の対気速度を適用することを可能とした。 XV-1は200 mph (320 km/h; 170 kn) の速度に達し、開発当時の1950年代の基準の平均的な従来型の回転翼航空機より高速であった。しかしチップジェット方式の燃費の悪さ、騒音の酷さ、複雑な構造を持つことによる整備のしにくさの問題が出た。その上、チップジェット方式を採用したために、高温高圧のガスや、強力な音波に伴う振動などを原因とした機体材料疲労を主な理由とする、材料工学上の限界のために、本計画は終了するに至った。 (ja) McDonnell XV-1 — американский экспериментальный винтокрыл двухбалочной конструкции c реактивным приводом несущего винта. (ru) McDonnell XV-1 adalah helikopter eksperimental yang dikembangkan untuk program penelitian bersama antara Angkatan Udara Amerika Serikat dan Angkatan Darat Amerika Serikat untuk mengeksplorasi teknologi untuk mengembangkan sebuah pesawat yang bisa lepas landas dan mendarat seperti helikopter dan terbang pada kecepatan yang lebih cepat, mirip dengan sebuah pesawat konvensional.
