![]() ![]() ![]() must it be fixed, or can you manage a variable nozzle arrangement). Hi Karen (and toller): would you be able to spare 5 or 10 mins to help me narrow down the questions my add-in needs to ask to produce useful ducts for people? Maybe post in the forum below (or reply by email to ): It would be useful to learn what kind of duct you want (I assume for a prop? if not - tell me!), and what information you already know (or can reasonably find out) about it (speed ranges, size, thrust needed, medium, etc) and how you intend to construct it (e.g. I'm able to give this away for free because another software product I wrote pays my wages indefinitely - that's the cool thing about software: write it well, and it works indefinitely for you, and you get to spend the money it earns for you :-) The 'back end' stuff runs on a cluster with 204 high-speed CPUs. Software is a great area to get into - especially if you've got 'the knack' (i.e. I'm able to give this away for free because another software product I wrote pays my wages indefinitely - that's the cool thing about software: write it well, and it works indefinitely for you, and you get to spend the money it earns for you :-) Thanks for the kind review! There are 3 parts to this app: the Fusion 360 add-in (written in Python), the particle-swarm and genetic optimizer (written in Perl), and the CFD solver (Written in Fortran - I kid you not).

A result of the analysis shows that the greater the flow turning, the greater the lift generated by an airfoil.Thanks for the kind review! There are 3 parts to this app: the Fusion 360 add-in (written in Python), the particle-swarm and genetic optimizer (written in Perl), and the CFD solver (Written in Fortran - I kid you not). The amount of lift generated by an object depends on how much the flow is turned, which depends on the shape of the object. Speeding up means the wings force more air downwards so lift is increase How does shape affect lift?Įffect of Shape on Lift. 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). The amount of lift depends on the speed of the air around the wing and the density of the air. A symmetrical wing has zero lift at 0 degrees angle of attack. Which type of airfoil produces the maximum lift at 0 degree angle of attack?Ĭambered airfoils are curved such that they generate some lift at small negative angles of attack. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Which part of a airplane produces the greatest amount of lift? Lift is caused by the faster movement of air on the top side of an airfoil. A portion of the lift is also provided by the lower surface that has higher pressure, but is much smaller in compariso Which type of airfoil produces the most lift?Īirfoil Three generated the most lift due to the oval arc shape. In subsonic flight, the majority of the lift is generated by the lower pressure (compared to ambient) at the upper surface of the airfoil, which produces a net suction. Which surface of the airfoil produces the most lift? Airfoils are used in the design of aircraft, propellers, rotor blades, wind turbines and other applications of aeronautical engineering. ![]() These wings provide good lift at low speeds, and they are structurally efficient, but are not suited to high speedĪirfoils are highly-efficient lifting shapes, able to generate more lift than similarly sized flat plates of the same area, and able to generate lift with significantly less drag. This kind of wing extends from the body of the airplane at right angles. Which airfoil produces the most lift at low speeds?Ī: The straight wing is found on a lot of low-speed airplanes. Cambered airfoils will generate lift at zero angle of attack. Increasing the camber generally increases the maximum lift at a given airspeed. As a fixed design, this type of airfoil sacrifices too much speed while producing lift and is not suitable for high-speed flight. The most efficient airfoil for producing the greatest lift is one that has a concave or “scooped out” lower surface. ![]()
