Lift is the vacuum produced by air traveling faster over the top of a wing than it does on it's underside. Welcome to part 6 of a series on an Introduction to Aircraft Design. Wing Design 4 One of the necessary tools in the wing design process is an aerodynamic technique to calculate wing lift, wing drag, and wing pitching moment. The amount of lift depends on the speed of the air around the wing and the density of the air. In part 5 we looked at the role that the airfoil profile plays in determining the flying characteristics associated with its selection. Blended Wing Body The blended wing body configuration is highly fuel efficient as it maximizes the lift of the entire airplane while also improving cabin size. Lift In order for an aircraft to rise into the air, a force must be created that equals or exceeds the force of gravity. Here are the 6 most common wing planforms out there.1) Rectangular wings stall from the root, but they create lots of induced drag at the tips. The wings of an aircraft are designed to lift it into the air. This force is called lift. HIGH-LIFT WING DESIGN. Speeding up means the wings force more air downwards so lift … In heavier-than-air craft, lift is created by the flow of air over an airfoil. The Wrights pioneered the concept of lateral (roll) control – one of their most important technical contributions to the airplane. Different wing planforms can typically be grouped into those used for low-speed flight, and those used for high-speed flight. The shape of an airfoil causes air to flow faster on top than on bottom. A reflex airfoil only produces lift in its forward part. When a wing generates aerodynamic lift, the air on the top surface has lower pressure relative to the bottom surface.Air flows from below the wing and out around the tip to the top of the wing in a circular fashion. The rear part produces a little downforce at high speed and proportionally much less lift than the forward part at low speed, so the whole wing will become less efficient. This wing orientation, unlike the blended wing body, typically allows for faster speeds (which improve lift) at the expense of smaller wings (which typically hinder lift). A short take-off and landing (STOL) aircraft must be able to fly at low controlled speeds, yet it must also offer acceptable cross-country (cruise) performance. It will be better to reduce wing area and to use an airfoil with an excellent ratio of lift to drag. Their particular design for any given aircraft depends on a number of factors, such as size, weight, use of the aircraft, desired speed in flight and at landing, and desired rate of climb. To produce more lift, the object must speed up and/or increase the angle of attack of the wing (by pushing the aircraft’s tail downwards). Thus, the aircraft is lifted into the air. Below, you can see how rectangular the Piper PA-23 Aztec's wing really is. The wing tips could be warped in opposite directions, setting up an unbalanced lift force on the two wings, and hence providing a control mechanism to roll the airplane. With the progress of the science of aerodynamics, there are variety of techniques and tools to accomplish this time consuming job.
