Experimental aircraft are designed in order to test advanced aerodynamic, structural, avionic, or propulsion concepts.

Several propulsion concepts are proposed that might be eventually developed to accomplish this, but none of them are ready for near-term (few decades) development at acceptable cost.

The laboratory remains a center of excellence in areas ranging from futuristic propulsion concepts to deep space communication.

He is currently working on several advanced propulsion concepts, very large space telescopes, space-based beamed energy systems, high-energy lasers, and next generation space launch concepts.

Sandia National Labs was responsible for qualification of the coated particle fuel for use in the SNTP nuclear thermal propulsion concept.

There are two basic solar thermal propulsion concepts, differing primarily in the method by which they use solar power to heat the propellant:

(The Institut für Kraftfeldphysik e.V. was intended to develop test models of his propulsion concepts.)

Well," Ael said, "since we left home space, Master Engineer tr'Keirianh has been experimenting with a propulsion concept our people came up with a while ago.

There, he managed a number of transportation technology programs including hybrid propulsion, electric propulsion, low-thrust chemical propulsion, and other advanced propulsion concepts (e.g., fusion, antimatter).
