Russian engineers develop new engine for ultra-light space rockets

 

MOSCOW, 13 April (BelTA - TV BRICS) - A team of Russian specialists is developing the NK-3 engine with a thrust of 4.5 tonnes for use in ultra-light launch vehicles. The propulsion system will operate on environmentally friendly fuel and incorporate a thrust vector control mechanism, enabling precise adjustment of the rocket’s trajectory. The development was announced by the United Engine Corporation, part of the state corporation Rostec.

The NK-3 engine will be used for the first and second stages of the "Voronezh" ultralight rocket. The first stage will use 12 engines, whilst the second will use a single engine.

According to the developers, the engine combines elements of existing technological solutions with newly designed components. The use of modern technologies will enable the rapid manufacture of parts and assembly units with varied designs, facilitating testing and, subsequently, the selection of the most efficient model.

Ultra-light launch vehicles are designed to deliver commercial payloads of up to 250 kilograms into Earth orbit. In this regard, as stated by the company’s deputy director, Mikhail Remizov, the development will expand the market for specialised services for the launch of small satellites and contribute to the advancement of the Russian space industry.
