I'm using the linear method".
The aerodynamic pressure is evaluated using the supersonic piston theory.
The aircraft successfully made five catapult takeoffs using the piston engine as well as three takeoffs using both engines.
Pressure was controlled to 1 atmosphere using the Nosé-Hoover Langevin piston method employing a piston period of 100 fs and a piston decay of 50 fs.
The linear plate theory is used for structural modeling, and linear piston theory is used for aerodynamic modeling.
The classical plate theory along with the von-Karman nonlinear strains is used for structural modeling, and linear piston theory is used for aerodynamic modeling.
A starting method of using the resonance characteristics of free-piston engine is simulated with different relatively small constant thrust forces and the designed free-piston engine could be started by the linear alternator.
Further, valves are made on the piston using the diamond tool followed by a rounding-off operation on the corners of piston.
5 days after piston insertion, 4 rats were subjected to motion-controlled loading of the piston using the materials testing machine (100 R; DDL Inc., Eden Praire, MN).
In this research, an experimental test rig of a dual-piston air-driven free-piston linear expander (FPLE) is established using the FPE concept.
