NASA’s Technology Transfer Program is licensing its rights to a extreme brand-new type of propulsion that utilizes electromagnets to control the circulation of plasma over airplane and spacecraft flying at hypersonic speeds.
As cars fly through a planetary environment at hypersonic speeds — at least 5 times faster than the speed of noise — they produce a circulation of charged gases. NASA’s principle includes 2 electrodes ingrained on the heat guard of an airplane or spacecraft, along with an electromagnet underneath the heat guard. The set of electrodes capture the electrical charge in the ionized circulation of gas exterior the craft, either to charge a battery or to power an electro-magnetic coil ingrained in the airplane or spacecraft. That’s where things get intriguing.
NASA states the electromagnet can then be utilized to control the circulation of gas around the automobile, either to minimize drag (atmospheric friction) or guide the automobile. This idea is based on what is understood as magnetohydrodynamics, or MHD, which utilizes electrical and magnetic fields to control the circulation of gases or liquids.
According to a notification the firm published on the federalgovernment contracting website SAM.gov on Thursday (Dec. 7), the innovation was established by scientists at NASA’s Langley Research Center in Virginia and hasactually been studied for usage in a simulated entry into Neptune’s environment. A different 2021 researchstudy of the exactsame innovation studied it for usage in the environment of Mars.

The firm declares its MHD system is “simpler than traditional techniques for control of hypersonic craft (e.g., chemical propulsion, moving flight center of gravity, or trim tabs) and allows brand-new entry, descent, and landing objective architectures.”
A different NASA declaration about the innovation declares it “harvests power through skimming of ionizing environments” and can assistance “larger, muchheavier craft into planetary environments (including Earth) at greater speeds.”
In March 2023, a group of global scientists moneyed by the Future and Emerging Technologies (FET) program of the European Commission explained a comparable MHD system as Langley’s, writing that sub-technologies such as high-temperature superconductors have “reached a level of commercial maturity enough for them to act as a secret allowing innovation for this application.”
NASA hasactually lookedinto comparable magnetohydrodynamic approaches for years, dating back to at least1965 A 2003 researchstudy carriedout by scientists at the company’s Marshall Space Flight Center in Alabama pointsout the long history of researchstudy into the subject at Langley, keepinginmind that “the NASA Langley program was an exceptionally effective effort.”
The U.S. Department of Defense has likewise checked and studied numerous techniques of steering and decreasing the drag knowledgeable by hypersonic automobiles for years. For example, the military hasactually lookedinto the usage of lasers to decrease the air density in front of a lorry and looked into leveraging the high rates of spin and vibration of electrically charged surfaceareas to attain comparable results as the system being certified by NASA Langley.
NASA welcomes business interested in licensing their innovation to use for a license the company’s Technology Transfer Portal at https://technology.nasa.gov/.
