The phrase "a fixed speed" is correct and usable in written English.
It can be used when referring to a speed that does not change or vary, often in contexts related to machinery, vehicles, or processes.
Example: "The car was designed to operate at a fixed speed of 60 miles per hour for optimal fuel efficiency."
Alternatives: "constant speed" or "steady speed".
To avoid this, computations are used in which the vehicle is assumed to travel at a fixed speed.
The design of a PID pitch angle controller for a fixed speed active-stall wind turbine, using the root locus method is described in this paper.
It identifies the range of flows and energy produced for a fixed speed, size, and design and suction conditions of the pump.
Abrasive wear tests were carried out on 5 vol.% SiCp and its matrix alloy against SiC and Al2O3 emery papers on a steel counterface at a fixed speed.
Enlightenment humanists tended to believe in absolute truths, of the kind produced by experimental science; they gave a fixed speed to light and asserted laws of gravity that were constant throughout the cosmos.
One had a clock hand that moved at a fixed speed in the usual manner, but with a dial whose time interval is adjusted to the temporal hour system.
In this paper, a model-based design methodology is introduced to study the performance gain of integrating a VRG into a fixed-speed stall-regulated wind turbine system.
To solve this mismatch, a specially designed, fixed-inverter hybrid heat pump system incorporating a fixed-speed compressor and an inverter-driven, variable-speed compressor was developed and tested in a real WWTP.
(a) Fixed-speed wind turbine; (b) DFIG; (c) full-converter wind turbine generator.
A 6-s current waveform measured during the soft starting of a fixed-speed wind turbine was analyzed.
Figure 2a shows a fixed-speed wind turbine system in which a squirrel-cage induction generator (SCIG) works in a speed-limited range above the synchronous speed.
