The Bell Aerosystems Lunar Landing Research Vehicle (LLRV) was an Apollo Project era program to build a simulator for the Moon landings. The LLRVs, humorously referred to as "flying bedsteads", were used by the FRC, now known as the NASA Dryden Flight Research Center, at Edwards Air Force Base, California, to study and analyze piloting techniques needed to fly and land the Apollo Lunar Module in the moon's low gravity environment.

- Das Lunar Landing Research Vehicle (kurz LLRV, engl. für Mondlandungs-Versuchsgerät) und das Lunar Landing Training Vehicle (kurz LLTV, engl. für Mondlandungs-Trainingsgerät) sind vom Dryden Flight Research Center der NASA im Rahmen des Apollo-Programmes entwickelte Fluggeräte zur Erforschung und Einübung einer manuell gesteuerten Landung auf dem Mond. Ihr spartanischer Aufbau als unverkleidetes Aluminiumrohr-Gestell brachte ihnen den Spitznamen „Flying Bedstead“ („Fliegendes Bettgestell“) ein.
- The Bell Aerosystems Lunar Landing Research Vehicle (LLRV) was an Apollo Project era program to build a simulator for the Moon landings. The LLRVs, humorously referred to as "flying bedsteads", were used by the FRC, now known as the NASA Dryden Flight Research Center, at Edwards Air Force Base, California, to study and analyze piloting techniques needed to fly and land the Apollo Lunar Module in the moon's low gravity environment. The research vehicles were vertical take-off vehicles that used a single jet engine mounted on a gimbal so that it always pointed vertically. It was adjusted to cancel 5/6 of the vehicle's weight, and the vehicle used hydrogen peroxide rockets which could fairly accurately simulate the behaviour of a lunar lander. Success of the two LLRVs led to the building of three Lunar Landing Training Vehicles (LLTVs) used by Apollo astronauts at the Manned Spacecraft Center in Houston, Texas, predecessor of NASA's Johnson Space Center. Nearly all of the flying bedsteads were destroyed in crashes, but the purpose built rocket ejection seat system recovered the pilot safely in all cases. The final phase of every Apollo landing was manually piloted by the mission commander. Because of navigational problems, Neil Armstrong, Apollo 11 commander, said his mission would not have been successful without extensive training on the LLRVs and LLTVs.
- Lunar Landing Research Vehicle ó LLRV, construido por Bell Aircraft Corporation, fue el nombre de una serie de vehículos experimentales con los que replicar el comportamiento del módulo lunar en la Tierra. Inicialmente fueron construidos dos vehículos de prueba, para posteriormente construir tres que entraron en producción, diseñados para el entrenamiento de astronautas en el pilotaje del módulo lunar, y que fueron denominados Lunar Landing Training Vehicles (LLTV). Un LLRV podía despegar y aterrizar por sus propios medios, volar horizontalmente, flotar sobre un punto y alcanzar alturas de hasta 1220 metros. Montaba un motor turborreactor que proporcionaba un empuje hacia arriba de 5/6 del peso del vehículo para simular el sexto de gravedad de la superficie lunar. Fue apodado humorísticamente somier volador, al consistir basicamente en un entramado de varillas. Los LLRV fueron creados por el predecesor del Dryden Flight Research Center (el Flight Research Center, FRC) de la NASA para estudiar y analiar las técnicas de pilotaje necesarias para hacer aterrizar al módulo lunar en la superficie sin atmósfera de la Luna. El éxito de los LLRV llevó a construir tres LLTV (Lunar Landing Training Vehicles), que fueron usados por los astronautas del programa Apolo como entrenamiento para las misiones lunares.
- Il Lunar Landing Research Vehicle, o LLRV (in italiano veicolo di atterraggio lunare di ricerca) era un veicolo costruito dalla Nasa, nell'ambito del programma Apollo, allo scopo di effetture i test di allunaggio e per permettere ai piloti di impratichirsi con le manovre necessarie per pilotare e far atterrare il modulo lunare Apollo in assenza di gravità. Fu originariamente prodotto, in due esemplari, presso il Dryden Flight Research Center, in California, ed in seguito al successo di questi modelli venne replicato, con varie migliorie, in tre Lunar Landing Training Vehicles, che vennero costruiti nel Lyndon B. Johnson Space Center di Houston. La particolarità di questo "strano" veicolo era quella di poter decollare ed atterrare verticalmente, perché dotato di reattori direzionabili molto potenti, cosa questa che permetteva agli astronauti di esercitarsi nei decolli e atterraggi; inoltre poteva essere pilotato come un elicottero perché dotato di barra centrale, che permetteva al veicolo di traslare lateralmente.

Il reproduisait le comportement en vol du module lunaire dans la gravité lunaire (1/6 de la gravité terrestre). Le LLRV a permis à la fois de mettre au point les procédures d'alunissage et de préparer les pilotes du module lunaire, avec un grand degré de réalisme, aux conditions de vol rencontrées lors de la phase d'atterrissage sur la Lune. Les derniers modèles furent appelés LLTV (Lunar Landing Training Vehicle).
