Ultralight aircraft, as a group, are designed primarily for recreational flying for distances of not more than 165.4 kilometers from a home base. Wing weight matters when we calculate its bending moment, but then we don't use the integral wing loading figure: we need the actual spanwise lift (and weight) distribution. Seems like pretty good economics for GA aircraft in my mind. Sergeant Russell E. Cooley IV), Figure 3 Explanation of Induced Drag (Click for large version). The faster an aircraft flies, the more liftcan be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. the latest revision. The engine is mounted in pusher configuration and turns the propeller through a reduction drive that uses a . These types consist of helicopters and gyroplanes. 800 LB. The basic idea of limiting the wing loading is to limit the stall speed and thus the destructive energy involved in a forced landing. No mention of Onan. others.

Forward sweep is definitely asking for trouble unless of course you happen to be structural engineer! Sadly for us, infinitely long wings are both tricky to build and hard to hangar, leaving finite wings as the only option. The 506 pound total carried on a 14.5 meter (47.6 feet) span equals a very light span loading of 10.6 pounds per foot.

Air speed isn't directly the input that decides if a foil fits your use. If you are chasing higher cruise speed, probably not. Different countries define ultralights in separate ways. How does wing aspect ratio influence lift and drag? This ultralight originally debuted in 1995, was discontinued for a while, and has since made a return with the Jordan Lake Aero company. Such as an extended fuselage to expand baggage space, strutted airframe components to increase the wing load rating, foldback wings for more accessible storage and transport, and so much more.

There are motors out there. Asking for help, clarification, or responding to other answers. Applications of super-mathematics to non-super mathematics. In reality the wing will be analysed using computational methods for many different loading combinations that exist at the edge of the aircraft design envelope and then subjected to a static test at the ultimate load factor to show that failure will not occur below the ultimate load. We all know that a wing produces lift by diverting the passing airflow. British fighter planes of WW2 were responsible for inflicting the first German defeat of the war, buying the Allies enough time to regroup and launch the vital Normandy offensive leading to The Axis surrender.
