In February 1976, work commenced to automate the methods contained in the USAF Stability and Control DATCOM, specifically those contained in sections 4, 5, 6 and 7.The work was performed by the McDonnell Douglas Corporation under contract with the United States Air Force in conjunction with engineers at the Air Force Flight Dynamics Laboratory in Wright-Patterson Air Force Base.
OpenVSP displays a graphical user interface upon launch, built with FLTK.A workspace window and a "Geometry Browser" window open. The workspace is where the model is displayed while the Geometry Browser lists individual components in the workspace, such as fuselage and wings.
MSC ADAMS (Automated Dynamic Analysis of Mechanical Systems) is a multibody dynamics simulation software system. It is currently owned by MSC Software Corporation. The simulation software solver runs mainly on Fortran and more recently C++ as well. [1] According to the publisher, Adams is the most widely used multibody dynamics simulation ...
Rotordynamics (or rotor dynamics) is a specialized branch of applied mechanics concerned with the behavior and diagnosis of rotating structures. It is commonly used to analyze the behavior of structures ranging from jet engines and steam turbines to auto engines and computer disk storage.
Joint Assistant for Development and Execution (JADE) is a U.S. military system used for planning the deployment of military forces in crisis situations. [1]The U.S. military developed this automated planning software system in order to expedite the creation of the detailed planning needed to deploy military forces for a military operation.
Sesam is a software suite for structural and hydrodynamic analysis of ships and offshore structures. [1] It is based on the displacement formulation of the Finite Element Method . The first version of Sesam was developed at NTH, now Norges Teknisk-Naturvitenskapelige Universitet ( NTNU Trondheim ), in the mid-1960s. [ 2 ]
The calculation of the speed ratios for a gear train with conjugate gear teeth becomes a calculation using the ratios of the radii of the pitch circles that make up the gear train. [15] Gear train design uses the desired speed ratio for a system of gears to select the number of gears, their configuration, and the size of their pitch circles.
The method uses similar concepts as the ACN-PCN method, however, the ACR-PCR method is based on layered elastic analysis, uses standard subgrade categories for both flexible and rigid pavement, and eliminates the use of alpha factor and layer equivalency factors. [2] The method relies on the comparison of two numbers:
