    摘要： A method, performed on at least one computing device, of determining solutions to a number of linear matrix equations satisfying A x = b , where A is a n × n matrix, x is a column vector with n entries, and b is a column vector with n entries, is disclosed. The method comprises determining a linear combination of unitary matrices that is equivalent to the matrix A ; based on the linear combination of unitary matrices, determining a column vector x that satisfies the linear matrix equation; forming an updated matrix A based on the obtained column vector x ; forming an updated column vector b based on the obtained column vector x ; updating the coefficients of the linear combination of unitary matrices based on the updated column vector x ; and based on the updated linear combination of unitary matrices, determining an updated column vector x that satisfies the updated linear matrix equation.

    摘要： A hydrogen-fuelled aircraft power system (300) incorporates a gas turbine engine (301) and a fuel cell (302), in which air supply and cooling of the fuel cell (302) is integrated with the gas turbine engine (301) to improve overall efficiency of the power system (300). The system may be part of a turbofan, turboprop or electric propulsion system for an aircraft.

    摘要： A system (100) and a method (900) of testing a specimen. The system (100) includes an endcap (102), a plurality of bars (104), a plurality of strain gauges (106), and a gas gun (108). The endcap (102) includes a first surface (202) and a second surface (204) opposite to the first surface (202). The first surface (202) is curved. Each bar (104) is disposed in contact with the second surface (204) of the endcap (102) and extends along a longitudinal axis (LA). Each strain gauge (106) is disposed on a surface (302) of a corresponding bar (104) from the plurality of bars (104). At least one strain gauge (106) is disposed on the surface (302) of each bar (104). The gas gun (108) is configured to fire a specimen (602) towards the first surface (202) of the endcap (102) such that the specimen (602) impacts the first surface (202) at an oblique angle (A1) relative to the longitudinal axis (LA).
