VASIMR is capable simple stirling engine plans pdf functioning in either mode. VASIMR concept and has been developing it since 1977.

VASIMR has been described as a convergent-divergent nozzle for ions and electrons. The second phase of the engine is a strong electromagnet positioned to compress the ionized plasma in a similar fashion to a convergent-divergent nozzle that compresses gas in traditional rocket engines. Resonance is achieved through a reduction of the magnetic field in this portion of the engine that slows the orbital motion of the plasma particles. Based on novel theoretical work in 2004 by Alexey V. This allows for ions to leave the magnetic nozzle with a very narrow energy distribution, and for significantly simplified and compact magnet arrangement in the engine. However, new problems emerge, such as interaction with strong magnetic fields and thermal management.

The relatively large power at which VASIMR operates generates substantial waste heat that needs to be channeled away without creating thermal overload and thermal stress. Important refinements were introduced to the rocket concept in the 1990s, including the use of the “helicon” plasma source, which replaced the plasma gun originally envisioned and made the rocket completely “electrodeless”—adding to durability and long life. In 1998, the first helicon plasma experiment was performed at the ASPL. 10 in 1998 achieved a helicon RF plasma discharge as great as 10 kW, VX-25 in 2002 as great as 25 kW, and VX-50 as great as 50 kW. VX-50 proved capable of 0. Ad Astra’s Board of Directors was formed and Díaz became chairman and CEO on July 15, 2005. In December 2006, AARC-Costa Rica performed its first plasma experiment on the VX-CR device, using helicon ionization of argon.

VX-100 plasma output tripled the prior record of the VX-50. Instead, efficiency losses emerged from the conversion of DC electric current to radio frequency power and the energy consumption of the auxiliary equipment for the superconducting magnet. The remaining 170 kW of power was allocated for acceleration of plasma in the second part of the engine, via ion cyclotron resonance heating. 5,000s using low cost argon propellant.
