  • Patent number: 10414485
    Abstract: The invention provides an improved propeller blade design by modifying a classic propeller blade design by changing the twist distribution across the propeller blade(s). This is accomplished by increasing the twist of each propeller blade on the inboard portion of the blade compared to a classic propeller design. At a break point, the twist provided across the propeller blade from the break point to the tip of the blade decreases so that the attack angle at the tip of the propeller blade is less than that of a classic propeller blade design.

  • Patent number: 10343131
    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 supercritical 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 aeorogel composite also can be used in thermal protection systems designed for fire protection for structures or in personnel fire protective equipment.

  • Patent number: 10337996
    Abstract: The present invention relates to a Lidar surveying instrument, which is capable of detecting and discriminating laser-induced particle fluorescence of any biological or non-biological atmospheric particles. The present astrobiology sensing instrument can remotely sense and discriminate, in real-time, the bio-indicator aerosol material signatures and environmental interferents that exist in an extraterrestrial environment, such as Mars, in order to expand the search for signatures of extraterrestrial life from the planetary soil to the planetary ground level atmosphere, by performing atmospheric volume scans of hundreds of meters in a radial direction around a planetary vehicle or a spacecraft. The Lidar instrument technology of the present invention employs real-time aerosol particle detection and discrimination based on two physical variables: particle fluorescence and particle size in the bio-discrimination space.
