Laser/Microwave Energy Deposition to Improve Control/Performance of High Speed Vehicles
In this effort, we will couple the energy of focused microwave bursts into the air and onto surfaces by first forming a laser plasma. The presence of the laser plasma allows much lower microwave intensities to couple their energy to the laser-pre-ionized surface or air-volume, allowing more efficient energy-transfer and the use of lower-power microwave systems to achieve the desired effect. We will use a variety of laser pulses, including ultrashort laser pulses, which can achieve the intensities required to seed surfaces and air, even with very little energy per pulse. This is a direct result of their short pulse width, and will allow very low average laser-power as the seed, relying on the more cost-effective microwave source for the bulk of the energy deposition. In this effort, our team will define energetically favorable high speed conditions, under which to implement laser-microwave discharges. We will also determine the test parameters required to test a slewing laser-microwave system that produces sculpted surface-volumetric discharges in quiescent and flowing air. Lastly, we will identify the plans for Phase II, to develop and demonstrate a laser-microwave system. BENEFIT: The benefits of this technology will increase control and performance on high speed air platforms, including military and civilian aircraft, as well as unmanned systems (including missiles and re-entry vehicles), and space access and re-entry craft. The potential absence of moving parts in the resulting control effectors stand to dramatically improve cost, risk, performance, and longevity.
