VSKYLABS UL-104 J/R


VSKYLABS UL-104 J/R Highly maneuverable Ultralight airplane
Original Design Valveless Pulsejet Powered Light Ultralight Airplane Prototype

The UL-104/J is a research prototype which designed for control and stability investigation of lightweight aircraft.



*** SORRY, BUT THIS AIRCRAFT IS UNDER UPDATE ***

Project overview:
The VSKYLABS UL-104/J is based on the UL-104 Ultralight bush plane. It's main design features are basically the same, pushing simplicity and agility a few steps forward:

Airframe:
Main wing with no moving surfaces (same as in the UL-104).

Tail section reduced from twin T-Tail's to twin elevons/rudderons. This feature simplifies tail structure, combining all aircraft controls. 
Controlling the aircraft is made by two large tail surfaces located at the aft portion of the tail-booms, coming out of the wingtips. These two tail surfaces, being far away from each other, acts as elevators, when moving together up/down, and acts as ailerons/rudders when moving in opposite direction. Because of their angle, roll moment is coupled with yaw moment, causing the plane to turn as if it's "auto-coordinated". This allow's it to turn tight, but also to side-slip. The side-slip is self restrained 
by the large, twin, semi-vertical tail surfaces.
Power Plant (UL-104-J version):
Two Valveless PulseJets, giving the UL-104/J cruise speed of about 100 Knots, and relatively high thrust at static/low airspeeds, as needed in short takeoffs
and tight maneuvers/short and steep landings.

Flying Tips:
There is no use of pedals for rudder - Crosswind handling with STICK to the wind.
"Jet Floater" version (sea plane): This is an Ultralight seaplane, So set waves height to 0.3 feet or below for safety...
(waves height setting is in the weather condition window in the simulation).
