摘要： A method comprising performing simulations to determine energy transfer between the bulk fluid motion of gases through a combustion chamber and resonant acoustic modes of the combustion chamber using a simulation model. The method also comprises configuring one or more combustion chamber parameters for the simulation model to shape the resonant acoustic modes to diminish coupling between the resonant acoustic modes and driving mechanisms at a head portion of the combustion chamber and to enhance coupling between the resonant acoustic modes and damping mechanisms at an aft portion of the combustion chamber. The method further comprises determining whether the combustion chamber meets a predetermined performance level in response to determining that the combustion chamber meets a predetermined combustion stability level.

摘要： A computer-implemented method for vehicle impact analysis including obtaining a B-Rep representing an outer surface of a vehicle, the B-Rep having faces and obtaining a radius value for a contact sphere. The method also includes determining one or more two-point-contact curves of the B-Rep for the radius value. The determining includes, for each respective two-point-contact curve, solving a respective differential equation based on the B-Rep. The method forms an improved solution for vehicle impact analysis.

摘要： A method of modeling a turbine mounted behind an aircraft wing for providing a specified proportion of a propulsive force in the aircraft flight direction to an amount of power generated by the turbine when driven by the airflow trailing the wings. The turbine converts a portion of the otherwise wasted energy in the rotational vortices trailing the aircraft wings into thrust that reduces aircraft drag while also providing electricity to power electrical systems on the aircraft. The method is also capable of modeling a turbine construction that will use the energy in the wake solely to generate electricity without increasing drag on the aircraft or solely to reduce drag without generating electricity. In one embodiment, the method saves computation time by using a recursive routine to define a preliminary turbine configuration based on an idealized vortex model and then matches it to the flow trailing an actual aircraft wing.

摘要： [Object] To realize an improvement in design accuracy and a reduction in design time in a process of matching an equivalent cross-sectional area of a design shape of a supersonic aircraft to a target equivalent cross-sectional area in a sonic boom reduction method based on an equivalent cross-sectional area.
[Solving Means] The technique includes: setting an initial shape of the airframe and a target equivalent cross-sectional area of the airframe; estimating a near field pressure waveform for the initial shape of the airframe assuming that the supersonic aircraft flies at a cruising speed; evaluating an equivalent cross-sectional area from the estimated near field pressure waveform for the initial shape of the airframe; and setting a Mach plane corresponding to the cruising speed, and setting a design curve on the Mach plane, the design curve corresponding to an initial curve at which the initial shape of the airframe and the Mach plane intersect so that the equivalent cross-sectional area approaches the target equivalent cross-sectional area. Then, the shape of the airframe is designed based on the design curve.

摘要： Methods, systems, and networks for controlling design and manufacture of mechanically and electrically compliant VCM-based vehicles, in which a user manually and explicitly defines at least one vehicle characteristic and at least one VCM characteristic. User selection of one or more vehicle characteristics ensures that the selection of VCM characteristics will be that of VCM characteristics compatible with the selected vehicle characteristics. Similarly, user selection of one or more VCMs or VCM characteristics ensures that the selection of vehicle characteristics will be that of vehicle characteristics compatible with the selected VCM or VCM characteristics.

摘要： A method and system provide the ability to generate models. A generative shelled base is created as a hollow computer-aided design (CAD) design. A t-spline mid-surface shell is created from the generative shelled base, which is then used to create a shell mesh model. A t-spline solid body is created from the generative shelled base, which is used to create an internal support structure that is converted into a shell CAD geometry, which is used to create a support structure mid-surface shell. The support structure mid-surface shell is combined with the shell mesh model into a generative mid-surface mesh that is used in a computer-aided engineering (CAE) crash simulation. The generated shelled base is combined with the shell CAD geometry into a generative shelled solid that is utilized in an additive build simulation.

摘要： A singular material detection apparatus (2000) acquires, for each of a plurality of materials (60), material specification information (10) representing material specifications of the material (60) and physical property information (20) indicating physical properties of a product (70) that can be generated by using the material (60). The singular material detection apparatus (2000) generates a self-organizing map (30) by using the physical property information (20). The singular material detection apparatus (2000) assigns each of pieces of material specification information (10) to one of nodes based on the physical property information (20) corresponding to that piece of the material specification information (10). Then, the singular material detection apparatus (2000) detects, from among the nodes to which the pieces of material specification information (10) are assigned, a singular node located at a singular position in a map space.
