To achieve the requested thrust output the design utilizes a mass flow sensor for real-time measurements of the gas flow in the feedback signal of the control loop of the flow control valve.
However, proportional thrust regulation would in principle increase the orbit keeping time as the thrust output could be adjusted according to variations in the atmospheric drag.
It is also capable of achieving efficient pipe lay rates for long trunk lines, operating in severe weather conditions, and providing significant thrust output
and power distribution.
GE has already increased the thrust output
the engine has to produce and more changes may still come, he added.
A high expansion ratio leads to low exhaust pressure, increasing the conversion of potential output (represented by the chamber temperature and pressure) to thrust output
(exhaust momentum and pressure).
During the next 40 years, he continued improving the engine's performance and thrust output
with the goal of creating a personal helicopter.
(in pounds) is given by the expression: F=2[pi]peNT, where p = drivescrew pitch (rev/in); e = drivetrain efficiency; N = reducer ratio; and T = input torque (lb-in).
In fact, we have already defined the engine growth steps to achieve a 25% increase in thrust output
in preparation for meeting future customer requirements.
The aircraft used is SSAC's FAA conformed SJ30-2 twinjet S/N 0004, using Williams Rolls FJ44-2A engines with thrust output
of 2,300 lbs each engine.
These tests include LiftFan runs at full power -- 29,000 hp input and over 20,000lb thrust output
-- and significant risk reduction testing.
In a fully-optimized engine design, thrust output
would be even greater and fuel consumption even lower.
Higher torque and thrust outputs
can also be provided for.
