例句与造句

1. Electromagnetic launchers such as launch loops might be feasible with current technology.
2. Some other Launch Loops are developed in.
3. Two variant designs based on the space fountain are the launch loop and the orbital ring.
4. In addition, launch loops themselves are not a significant source of space debris, even in an accident.
5. The space cable design uses discrete bolts rather than a continuous rotor, as with the launch loop architecture.
6. It's difficult to find launch loops in a sentence. 用launch loops造句挺难的
7. Launch loops in Lofstrom's design are placed close to the equator and can only directly access equatorial orbits.
8. Arched fountain structures similar to the launch loop could also have useful small-scale applications, notably the construction of bridges.
9. Launch loops are intended to achieve non-rocket spacelaunch of electromagnetically accelerating them so that they are projected into Earth orbit or even beyond.
10. Lofstrom's launch loops are expected to launch at high rates ( many launches per hour, independent of weather ), and are not inherently polluting.
11. Launch loops were described by Keith Lofstrom in November 1981 Reader's Forum of the American Astronautical Society News Letter, and in the August 1982 L5 News.
12. Other proposed ideas include ground accelerators such as launch loops, rocket assisted aircraft / spaceplanes such as Reaction Engines Skylon, scramjet powered spaceplanes, and RBCC powered spaceplanes.
13. A "'launch loop "'or "'Lofstrom loop "'is a proposed system for momentum of a belt that circulates around the structure.
14. To access circular orbits using a launch loop a relatively small'kick motor'would need to be launched with the payload which would fire at apogee and would circularise the orbit.
15. Unlike space elevators which are subjected to the risks of space debris and meteorites along their whole length, launch loops are to be situated at an altitude where orbits are unstable due to air drag.
16. The Lofstrom launch loop or a space elevator hypothetically provide excellent solutions; in the case of the space elevator, existing carbon nanotubes composites, with the exception of possibly Colossal carbon tubes do not yet have sufficient tensile strength.
