Calculate the lift curve slope for a NACA 23012 wing of 2-D lift curve slope = 0.106 per degree, aspect ratio = 10, Re = 5 x 10 6 and span effectiveness factor = 0.95. The goal here is primarily to see if the total package is positively buoyant. Theory The Wing Scale loading is a method of acounting for the size to weight ratio changes in wing loading as the size (scale) of the model changes, and is calculated by dividing the weight of the model by the wing area multiplied by the square root of the wing area and adjusted for scale factor by raising to the .8 power. Enter Wing Area, (sq in) Enter Model Weight in oz. Wing loading is a measurement that relates the mass of an aircraft or bird to the total wing area. The relationship between wing area and body weight is given in kilograms per square metre (or grams per square centimetre). Wing Loading Wing Loading (W/S) • The term “Wing Loading” normally refers to the takeoff Wing Loading as was the case with Thirst-to Weight Ratio.

The thrust-to-weight ratio (TWR) is a ratio that defines the power of a craft's engines in relation to its own weight. Just find a motor/prop combination that can provide more thrust than the weight of the quadcopter. Keep in mind that for an agile aircraft you generally you want it to hover at 50% throttle or lower. The following procedure can be used for a simple, tapered and, swept wing. Equipment weight. Quadcopter weight calculator formula.

We can also calculate the spanwise location of the mean chord , using the span b,. For longitudinal stability the CG is placed 5% to 15% of MAC in front of the NP. We depend on donations from exceptional users, but fewer than 2% give. In this class the propulsion system and battery weight is given; the control system weight is known, and you must estimate the fuselage, tail, and wing weights. The third step in the design process is the detail design. More importantly though is that the best glide speed does depend on the aircraft weight even though the maximum glide distance does not . Aspect ratio is a measure of the ratio between the span of the wing to its chord. In most cases the wing chord is not equal along the length of the span (untapered) which is why aspect ratio is most commonly calculated by dividing the square of the wing span by the reference wing area.
