For the variable compression ratio, the brake torque is kept constant at its maximum value of 295 N.m over a speed ranging from 1,500 to 2,460 rpm by varying the compression ratio between 16.4 and 19.3.
These materials were tested in single edge notch tensile tests as a function of test speed over a test speed range of 10−4 10 m s−1(2.85×10−3–2.85×102 s−1).
The doubledelta platform was adopted to provide minimal change of the aerodynamic center over a broad speed range, and also to provide a large strake to hold fuel and oxidizer so that the center of gravity does not move as the propellant is consumed.
Other notable advantages include increased spark plug life, improved firing over a wider speed range, and better moisture tolerance.
For example the design and operation of the cage can ensure fully flooded lubrication over a wide speed range.
The engine is tuned to operate over a narrow speed range, using the least gas and producing the smallest amount of pollutants.
These hydrodynamic and mass transfer characteristics were investigated over a rotor speed range of 8 40 r/s and the annular gap in the range of 2 25 mm.
As a result, the proposed method makes it possible to achieve good motor performance over a wide speed range and to simplify the starting procedure.
Rate-dependent large deformation behavior of the alloy of polycarbonate and acrylonitrile butadiene styrene (PC/ABS) is experimentally investigated over a crosshead speed range of 1 3000 mm/min.
The novel features include evaluating the stick-slip behaviour and dynamic coefficient of friction over a wide speed range from 0.1 to 6000 mm/min under load.
