by Mark D. Bowles and Virginia P. Dawson. Ina Washington Post headline read, "The aircraft engine of the future has propellers on it." 1 To many this statement was something like heralding "the reincarnation of silent movies." 2 Why would an "old technology" ever be chosen over a modem, new.
The design has several important benefits that excite plane makers like GE’s launch customer, Textron Aviation, which will use the ATP for a brand-new business seater called Cessna lly, pilots fly turboprop planes using three levers: one for fuel, another for controlling the pitch of the propeller, and a third for power.
ATR is evaluating the use of the ClearVision enhanced vision system in low visibility conditions. The French OEM took a prototype ATR aircraft to Guernsey in June for final testing of the system.
Graphical analysis is used to examine the complex vortical patterns in each component, identifying sources of pressure loss. The simulations demonstrate the importance of including the rotating high-pressure turbine blades in the computation, as this results in direct computation of combustion within the first turbine stage, and accurate simulation of the flow in the second combustion by: 3.

As mentioned on a previous page, propeller engines develop thrust by moving a large mass of air through a small change in velocity.
Propellers are very efficient and can use nearly any kind of engine to turn the prop (including humans!). In the turboprop, a gas turbine core is used.
