Latest Patents

One of his latest patents is the "Hypersonic Aircraft Window System." This system and method are designed for sending signals at temperatures associated with hypersonic speeds. The window system comprises a transmissive window in the aeroshell of the hypersonic aircraft, a thermal seal, a sensor, and a sensor housing assembly enclosing the sensor. The transmissive window consists of a facesheet and insulating material adjacent to the facesheet. The thermal seal surrounds the perimeter of the facesheet and seals it to the aeroshell. Notably, the window system is radio-frequency transparent at hypersonic speeds and is configured to operate at an insertion loss of less than one decibel.

Another significant patent is for "Reworking Ceramic Sandwich Structures." This method involves removing a portion of a first facesheet from the ceramic structure to form a first aperture. The first facesheet comprises multiple layers of a first ceramic material. A portion of the inner section of the ceramic structure is also removed to create a second aperture, which extends from the first aperture into the inner section. The inner section consists of a second ceramic material bonded to the first facesheet and has a lower density than the first facesheet. A ceramic replacement material is then placed in the second aperture, and several replacement ceramic layers are added in the first aperture. Ceramic particles are sintered to bond these layers to the first facesheet.
