![]() Here is how the Induced drag coefficient given aspect ratio calculation can be explained with given input values -> 0.047746 1.52/ (pi15). The wingspan of the airplane is entered in imperial (inches) units.ĭISCLAIMER: Please use this airplane design calculator for informational purposes only. To use this online calculator for Induced drag coefficient given aspect ratio, enter Lift Coefficient origin (Corigin) & Wing Aspect Ratio (AR) and hit the calculate button. Next, enter the wingspan of the airplane you plan to design and make. To use the calculator simply select the type of airframe that you are building. Using the RC Airplane Design CalculatorĮach calculated parameter can be reviewed in the image below to better understand where the dimensions are measured from. For instance, a 6×4 inch image has an aspect ratio of 3:2, whereas a 1920×1080 pixel video has an aspect ratio of 16:9. You’ll recognize it as two numbers separated by a colon in an x:y format. This requires the main airplane wing to be rectangular in shape when viewed from above and as pictured below. The aspect ratio of an image or video is the proportional relationship of the width to the height. Method 1 Divide the wing span by the average wing chord. This airplane design calculator assumes that the shape of the wing is of a constant cross sectional area. There are two ways to calculate the Aspect Ratio of a flight surface. In order to calculate the C Do of each aircraft, equation 4.60 is employed for the jet aircraft and equation 4.62 is used for the prop-driven aircraft. Building with foam board allows a lightweight, inexpensive and easy to build airplane. power of the prop-driven aircraft are all around 2000 hp/engine, and then thrust for the jet aircraft is around 8000 lb/engine. The plots are used to verify the best glide calculations. The recommended build material when using the design parameters for the RC airplane design calculator is foam board. These plots show drag and lift-drag ratio plots for the aircraft as a function of KCAS. Recommended Build Specifics – RC Airplane Design Calculator DISCLAIMER: Please use this airplane design calculator for informational purposes only. In most cases the wing chord is not equal along the length of the span which is why aspect ratio is most commonly calculated by dividing the square of the wing span by the reference wing area. The wingspan of the airplane is entered in imperial (inches) units. A wing’s Aspect Ratio is a measure of the ratio between the span of the wing and its chord. This ratio of pounds of thrust, which is equal to pounds of drag in steady state level flight, to the weight of the plane should give a good approximation of the glide ratio. Use this airplane design calculator to help you determine key airframe dimensions along with an approximate target weight and power for your radio control aircraft. To use the calculator simply select the type of airframe that you are building. The RC airplane design calculator has been created in order to provide an approximation of specific airframe parameters. change in this section, be sure to also click the Weight & Balance calculation button, too. ![]()
