  • Patent number: 10633256
    Abstract: Aerogels, aerogel composites and methods of making the same are discussed. One example method can include the act of creating a Boehmite colloid and adding a hydrolyzed silicon precursor to form a sol. A reinforcement can be infused with the sol, gelled to form a gel, then dried to form an aerogel composite. Such a method can also include the acts of performing one or more solvent exchanges and subjecting the gel composite to subcritical drying. Additionally, such a method can include the act of heat treating the aerogel composite. The aerogel composite can be used in high temperature, flexible seals capable of withstanding temperatures, pressures, and compression levels associated with aerodynamic heating generated during flight and in aerospace applications. The aerogel composite also can be used in thermal protection systems designed for fire protection for structures or in personnel fire protective equipment.

  • Patent number: 10612911
    Abstract: A method and system for rendering the quaternion shape and orientation of a three-dimensional structure. The proposed system and method keeps track of twist/roll angles and updates its effect on pitch and yaw orientations. The system relies on a single or multi-core optical fiber or multi-fiber bundle containing fiber Bragg grating sensors (FBGs) arrayed in rosettes at 45° deltas and spaced at uniform intervals along the entire length of the structure to be monitored. A tunable laser is used to interrogate the sensors using optical frequency domain reflectometry (OFDR), which detects shifts in the wavelength reflected by the sensors in response to strain on the fibers. Each sensor is continuously queried by software which determines the strain magnitude (?L/L) for each fiber at a given triplet. Given these measured strain values, the software implements a novel quaternion approach to rendering the 3D shape of the fiber including twist.
