米国的航天飞机设计中,整个动力系统的设计分成三个主要部分:Space Shuttle Main Engines (航天飞机主发动机), Solide Rocket Boosters (固体火箭推进器), Orbiter Maneuvering System (轨道器机动系统)。 其中SSME(Space Shuttle Main Engines)是位于Orbiter轨道器后部的三台液体发动机, SSME的燃料(fuel)和氧化剂(...
The Space Shuttle 航天飞机 I-02 / 002 Space shuttles go back and forth between Earth and space. The first one flew on April 12, 1981. A space shuttle has four main parts. They are the orbiter, the fuel tank, and two rocket boosters. The orbiter looks like an airplane. It carries th...
A seal in the shuttle’s right solid-fuel rocket booster designed to prevent leaks from the fuel tank during liftoff weakened in the frigid temperatures and failed, and hot gas began pouring through the leak. The fuel tank ...
Space shuttle, partially reusable rocket-launched vehicle designed to go into orbit around Earth, to transport people and cargo to and from orbiting spacecraft, and to glide to a runway landing on its return to Earth’s surface. It was developed by NASA
Buran, Soviet orbiter similar in design and function to the U.S. space shuttle. Designed by the Energia aerospace bureau, it made a single unmanned, fully automated flight in 1988, only to be grounded shortly thereafter due to cost overruns and the colla
The space shuttle was designed to carry large payloads into orbit, service them, and bring them back to Earth if necessary.
The external fuel tank includes the main engines, twin solid rocket boosters, and the orbiter. At 27.6 feet wide and 154 feet tall, the external fuel tank is the biggest element of the space shuttle, and it is the only part that cannot be reused. The aluminum skin of the tank is a ...
Such wonders as a space shuttle launch or astronauts walking on the Moon are incredibly exciting and inspiring to witness, and it can be these moments that shape children' s lives forever and motivate them to become the scientists and engineers of the future. It is this kind of inspiration ...
In contrast, the US-developed space shuttles are reusable space transport vehicles. The shuttles are launched vertically like a rocket,orbit like a satellite, and land just like an airplane. Each shuttle consists of a reusable orbiter, a large expendable external fuel tank, and a pair of reusab...
The problem began with exceptionally cold weather, which prevented a rubber O-ring on one of the shuttle's solid rocket boosters from maintaining its seal, allowing hot gas to leak and damage the shuttle's external fuel tank and the hardware attaching the booster to the vehicle. The right ...
