I chose it because of its reputation and the fact that we have a grass field at my club. The TGA uses a Byron's fan and rotates off the grass in about 350', our runway is around 900' long. The TGA was easy to build and easier to fly. I liked it so muchThis type is generally used with ducted turbofan engines, where the fan and core flow mix in a common nozzle before exiting the engine. The clamshell-type or mechanical-blockage reverser operates to form a barrier in the path of escaping exhaust gases, which nullifies and reverses the forward thrust of the engine. However, when learning that these benefits don't translate over into horizontal flight due to the duct's induced drag and pitching moment, I'm wondering if we'll ever see ducted fans in future aircraft. I'm aware of the NASA ducted fan manned-aircraft project that failed in the 60's, but today I found out about AgustaWestland's Project Zero and ...A ducted fan will be quieter for a given power level; because sideline noise, which is the worst part of a fan's or propeller's noise signature, is largely captured by the shroud. 4. A ducted fan usually runs at higher rpm than a bare propeller, which helps to make the ducted fan a good match for a high speed engine. 5.RC Jets - DUCTED FAN JETS - Originally Posted by gino_eior Hello, I want to build a jet plane with two Ramtech ducted fan units.
