(一)日本三菱电机公司正在进行若干项新技术研究,其中包括先进的推进系统:一种氙为燃料的高性能离子发动机(Melco),其比冲为31250m/s.它将于1992年用于H-2助推器发射的工程试验卫星ETS-6上.(A·W.＆S·T.86.8.)(二)1986年在英国法恩巴勒航空展览会上展出几个未来航天飞机的概念模型.西德MBB公司的Sanger是两级有翼的航天飞机.第一级是一架驮运飞机,是未来高超音速的航天飞机前身,第二级是叫做Horus的火箭发动机推进的飞机,在35km高度M为6.
(A) Mitsubishi Electric Corporation of Japan is conducting a number of new technology research, including advanced propulsion system: a xenon-fuel high-performance ion engine (Melco), its specific impulse of 31250m / s. It will be used in 1992 On the engineering test satellite ETS-6 launched by the H-2 booster. (A) W. & S. T.86.8. (II) Several future aerospace exhibitions at the Farne Islands Air Show in 1986 Conceptual model of the aircraft. The Sanger MBB Sanger is a two-stage winged space shuttle. The first stage is a pack of planes, the predecessor of the future hypersonic space shuttle, the second stage is the rocket engine called Horus propulsion Plane, M is 6 at a height of 35km.
