Black arrow launch vehicle

The black arrow launch vehicle is a launch vehicle developed by the UK. The black arrow has become the only successful launch vehicle in the UK, and its satellite has become the first and last satellite launched by the UK itself. The black rocket launch vehicle is a three-stage series test launch vehicle with the first and second stages of liquid rocket and the third stage of solid rocket. It was developed on the basis of the second stage research rocket "heiqitu". The former two stages are directly improved by the "Black Knight". The engine system uses the gamma liquid rocket engine of the "Black Knight earth" rocket. This engine has also been used on the first British intercontinental ballistic missile, the "blue light" and the "Europe" launch vehicle developed by the "European launch vehicle development organization". The inheritance and generality of this kind of design is that it makes use of mature technology, shortens the development cycle and reduces the cost.
