Испытания плазменных двигателей для межпланетных перелётов КМ-50М и ИД-750 прошли в Центре Келдыша

Russia has taken a step towards conquering deep space: the Keldysh Center has completed the development and testing of two unique high-power plasma engines. These installations will form the basis of future missions to the Moon, Mars, and even the distant planets of the Solar System.

The new engines — the Hall thruster KM-50M and the ion thruster ID-750 — have no global analogues. The first was created using magnetic shielding technology and is capable of operating for more than 20,000 hours. The second uses carbon-carbon composites and demonstrates a record resource of over 50,000 hours. Both engines run on inert gases — xenon and krypton, which are safe and suitable for long-term storage in space.

KM-50M develops thrust up to 1.6 Newtons and a specific impulse of 4200 seconds, and its modular tests in a vacuum confirmed the possibility of cluster application. ID-750, with a power of 80 kW, accelerates plasma to a speed of 100 km/s, which opens the way to interplanetary flights in a short time. Testing of three such installations at once proved their reliability and stability.

To operate such powerful systems, a compact nuclear power source is required. Specialists have already created a prototype turbine unit that converts reactor heat into electricity. It is capable of delivering the necessary power for cruise engines, which makes long-distance expedition projects a reality.

The transition from chemical engines to plasma engines makes it possible to increase the payload capacity of spacecraft, speed up flights, and reduce the cost of space exploration. For Russia, this is a chance to maintain leadership in electric propulsion technologies.
