Engineous
A new software system called Engineous combines artificial intelligence and numerical methods for the design and optimization of complex aerospace systems. Engineous combines the advanced computational techniques of genetic algorithms, expert systems, and object-oriented programming with the conventional methods of numerical optimization and simulated annealing to create a design optimization environment that can be applied to computational models in various disciplines. Engineous has produced designs with higher predicted performance gains that current manual design processes - on average a 10-to-1 reduction of turnaround time - and has yielded new insights into product design. It has been applied to the aerodynamic preliminary design of an aircraft engine turbine, concurrent aerodynamic and mechanical preliminary design of an aircraft engine turbine blade and disk, a space superconductor generator, a satellite power converter, and a nuclearpowered satellite reactor and shield.

Engineous
Engineous Software, Inc. provides process integration and design optimization software solutions and services. The company's iSIGHT software integrates key steps in the product design process, then automates and executes those steps through design exploration tools like optimization, DOE, and DFSS techniques. The FIPER infrastructure links these processes together in a unified environment. Through FIPER, models, applications and "best" processes are easily shared, accessed, and executed with other engineers, groups, and partners. Engineous operates numerous sales offices in the U.S., as well as wholly owned subsidiaries in Asia and Europe. Customers include leading Global 500 companies such as Canon, General Electric, General Motors, Pratt & Whitney, Honeywell, Lockheed Martin, Toshiba, MHI, Ford Motor Company, Chrysler, Toyota, Nissan, Renault, Hitachi, Peugeot, MTU Aero Engines, TRW, BMW, Rolls Royce, and Johnson Controls, Inc.
