How do you calculate cubic wing loading?
This is calculated by taking the weight of the plane and dividing by the wing area. A good rule of thumb is for a 40 size trainer one would expect a wing loading of about 16oz/sq ft and will be a docile flier.
How much weight can a wing hold?
The wings are very strong, able to carry the wight of at least 2.5 planes, usually 6 planes, some of them can carry the weight of 9 or 12 planes and more. Normal Category is a certification that has a maximum G loading of +3.8 G’s (positive G’s) -1.52 G’s (negative G’s).
What is the wing per square foot loading?
Wing loadings are figured by dividing the wing area of your plane by 144 to convert square inches to square feet. Then divide the weight of your airplane by your wing area in square feet.
What is wing cube load?
Wing Cube Loading (WCL) is a value that provides a consistent comparative numeric value, which can be used as a general indicator of the flying characteristics of a model radio controlled airplane. WCL is not dependent on size.
How do I choose wing loading?
The faster an aircraft flies, the more lift can be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. Consequently, faster aircraft generally have higher wing loadings than slower aircraft. This increased wing loading also increases takeoff and landing distances.
How do you find the CG of a wing?
Center of gravity (CG) is calculated as follows:
- Determine the weights and arms of all mass within the aircraft.
- Multiply weights by arms for all mass to calculate moments.
- Add the moments of all mass together.
- Divide the total moment by the total mass of the aircraft to give an overall arm.
How to calculate wing loading of a flying model aircraft?
How to Calculate Wing Loading. In this example, we will use an aircraft weighing 5-1/2 lbs (5 lbs 8 oz.) with 600 square inches of wing area. Calculating the wing loading requires that the wing area be converted to square feet (ft 2) and pounds to ounces. 1) Convert the area to square feet. There are 144 (12 x 12) square inches in a square foot.
How big is the wing load of a hang glider?
A typical hang-glider may have a maximum wing loading of 6.3 kg/m 2. On the heavy side, a Boeing 747 has a maximum wing loading of about 730 kg/m 2. Although it has a huge wing load, it can fly because of its incredible speed. Different wing shapes and sizes correspond to different flight capabilities.
How is wing loading related to body size?
Wing loading. 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).
What should be the wing loading of a bird?
Wing loading for birds is generally between 1 to 20 kg/m 2. The maximum possible wing load before a bird is unable to fly is about 25 kg/m 2. This is when the bird is too heavy for its wings (like the kiwi, which has tiny wings and a large body mass). The wing loadings of some of the lightest planes fall within the bird range.
