A space elevator, also referred to as a space bridge, star ladder, and orbital lift, is a proposed type of planet-to-space transportation system, [1] often depicted in science fiction. The main component would be a cable (also called a tether) anchored to the surface and extending into space. An Earth-based space elevator would consist of a ...
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft ...
A space elevator would consist of a cable anchored to the Earth's surface, reaching into space. A space elevator is a proposed type of space transportation system. [34] Its main component is a ribbon-like cable (also called a tether) anchored to the surface and extending into space above the level of geosynchronous orbit. As the planet rotates ...
Climbing elevator. A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance.
An inclined elevator is a form of cable railway. Users with mobility and disability challenges often use an incline platform lift to climb staircases in their home with their mobility scooter or motorized wheelchair. Outdoor inclined elevators are used to access steep hillside property where stairs are not a preferred option for conveying ...
Stabilizer (aeronautics) Vertical and horizontal stabilizer units on an Airbus A380 airliner. An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, [1][2] that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable ...
StarTram is a proposed space launch system propelled by maglev technology. The initial Generation 1 facility is proposed to launch cargo only from a mountain peak at an altitude of 3 to 7 kilometres (9,800 to 23,000 ft) using an evacuated tube remaining at local surface level. Annual orbital lift was estimated at approximately 150,000 tons.
Elevators using hoist ropes, however, could only function effectively in low-rise buildings, and this limitation encouraged the introduction of the hydraulic elevator in 1870, even though early models contained dangerous design flaws. [40] By 1876 these problems had been resolved, providing a solution for servicing the early skyscrapers. [41]
