- G. Hawkins and J. Murdock, “Combustible Outgassing Material Lined Altitude Compensating Rocket Nozzle,” U.S. Patent No. 7,815,146, Oct. 2010.
- Rocket boosters typically use a nozzle with an outlet pressure selected to optimize average performance during launch. This is not the most efficient setup because these nozzles typically overexpand the exhaust gases at liftoff and then underexpand them at high altitudes. Better performance could be obtained by continuously varying the outlet pressure during ascent. This invention allows a bell-shaped rocket nozzle to do so. The interior of the nozzle is lined with a thin layer of combustible material, which is ignited by the rocket engine exhaust. The gases produced travel down the nozzle and create an outgassing pressure plane inside the nozzle approximately equal to the external atmospheric pressure. The matched exhaust pressure from the nozzle to atmosphere over a large range of altitudes increases the lift performance of a rocket engine without additional mechanical parts. The combustible material is relatively inexpensive and does not add significant weight. The material thickness, position, and taper can be selected to optimize the lift capability of the rocket.
- Y. Chan, J. Camparo, S. Karuza, et al., “Precision Frequency Change Detector,” U.S. Patent No. 7,847,597, Dec. 2010.
- GPS satellites use atomic frequency standards to generate signals with precise frequencies. Atomic frequency standards are known for their precision and stability; however, they can suffer frequency jumps caused by their environment and external/internal clock physics perturbation. This fractional error can cause a much larger user error, especially if undetected and allowed to compound. Currently, frequency change detectors are located on the ground. This patent describes a change detector that can be installed onboard to autonomously and continuously monitor and solve frequency jumps or changes in frequency standard. The device operates by splitting a frequency standard into two replica signals. One replica signal is maintained, while the other is delayed by a predetermined amount. The two replica signals are then mixed together to form a mixed-frequency signal, which is filtered and amplified. The output detection signal indicates any change in the frequency.
