17K-AM
17K-AM was the name of a two-stage-to-orbit russian orbital launch vehicle projected in 1993, proposed by the Russian Air Force and to be constructed by Chelomey. It didn't pass the phase of study. The vehicle was to be composed by a Horizontal takeoff, horizontal landing launch stage with a spaceplane mounted on it that would reach orbit In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as ....

NPO Mashinostroyeniya
NPO Mashinostroyeniya (russian: НПО машиностроения, lit=RDA of machine manufacturing) is a rocket design bureau based in Reutov, Russia. During the Cold War it was responsible for several major weapons systems, including the UR-100N Intercontinental ballistic missile and the military Almaz space station program. India is Mashinostroyeniya's second largest customer after the Russian Federation for sale of P-70 Ametist, BrahMos, BrahMos-II and P-800 Oniks. History NPO Mashinostroyeniya was founded in 1944 to develop rockets for the Russian military. Under the leadership of cruise missile designer Vladimir Chelomey, the firm was lead developer of the Soviet Union's space satellites, cruise missiles, and intercontinental ballistic missiles. Originally part of the OKB-51 design bureau, it relocated to Reutov, and from 1955 to 1966 was designated OKB-52 (and also OKB-52 MAP). OKB-52 became later known as TsKBM. The OKB-52 was the main rival of OKB-1 (then the design b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stage-to-orbit
A two-stage-to-orbit (TSTO) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (SSTO) launcher. At liftoff the first stage is responsible for accelerating the vehicle. At some point the second stage detaches from the first stage and continues to orbit under its own power. An advantage of such a system over single-stage-to-orbit is that the most of the dry mass of the vehicle is not carried into orbit. This reduces the cost involved in reaching orbital velocity, as much of the structure and engine mass is ejected, and a larger percentage of the orbited mass is payload mass. An advantage over three or more stages is a reduction in complexity and fewer separation events, which reduces cost and risk of failure.

Orbital Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pads, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are classified by their orbital payload capacity, ranging from small-, medium-, heavy- to super-heavy lift. Mass ...

Horizontal Takeoff, Horizontal Landing
Aircraft can have different ways to take off and land. Conventional airplanes accelerate along the ground until sufficient lift is generated for takeoff, and reverse the process to land. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier jump jets can take off and land vertically. Rockets also usually take off vertically, but some designs can land horizontally. Horizontal takeoff and landing Aircraft Conventional takeoff and landing (CTOL) =Takeoff= Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground (taxiing) to flying in the air, usually starting on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier), no runway is needed. Takeoff is the opposite of landing. =Landing= Landing is the last part of a flight, where a flying aircraft or spacecraft (or animals) returns to the ground. Wh ...

Spaceplane
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered but then landed as unpowered gliders. Four types of spaceplanes have successfully launched to orbit, reentered Earth's atmosphere, and landed: the U.S. Space Shuttle, Russian Buran, U.S. X-37, and the Chinese CSSHQ. Another, Dream Chaser, is under development in the U.S. As of 2019 all past, current, and planned orbital vehicles launch vertically on a separate rocket. Orbital spaceflight takes place at high velocities, with orbital kinetic energies typically at least 50 times greater than suborbital trajectories. Consequently, heavy heat shielding is required ...

Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

Air Launch To Orbit
Air launch to orbit (ALTO) is the method of launching smaller rockets at altitude from a heavier conventional horizontal-takeoff aircraft, to carry satellites to low Earth orbit. It is a follow-on development of air launches of experimental aircraft that began in the late 1940s. This method, when employed for orbital payload insertion, presents significant advantages over conventional vertical rocket launches, particularly because of the reduced mass, thrust, cost of the rocket, geographical factors and natural disasters. Air launching has also been developed for sub-orbital spaceflight. In 2004 the Ansari X Prize $10 Million purse was won by a team led by Burt Rutan's Scaled Composites, launching the SpaceShipOne from the purpose-built White Knight carrier aircraft. Advantages The principal advantage of a rocket being launched by a high flying airplane is that it needs not fly through the low, dense atmosphere, the drag of which requires a considerable amount of extra work a ...
