what do they use. I made a small helicopter. HOW DO I BALANCE IT.? i don't wana put more weight to balance it. i want to find the center point of the helicopter.
how do engineers do it.
plz explain
DEsperate person.|||I presume you mean "Boeing," so I will hold off, for the present, on the first 50 jokes that come to mind about "boing" airplanes.
Airplanes are designed to balance around a particular point. When engineers lay out the initial design of an airframe, they estimate the weight of the structure and contents on "stations" every 10 feet or so along the length of the hull.
This enables the designer to come up with a rough idea of where the balance point will be, and to build a "balancing model" that can be balanced by adding and positioning small weights.
When the overall design has been refined to place the balance point in the general area where the designer wants it to be, the process begins of measuring the exact distance of each component of the airplane from a "datum point," which is usually right at the tip of the nose.
Each part of the airplane and device to be installed then has a "datum component" consisting of the weight of the object and its distance from the datum point. Datum components are expressed in foot-pounds, inch-ounces, newton-meters, or similar compound units.
After all the components are charted, it becomes possible to calculate the exact balance point by finding the median distance for all the components from the datum point. This can be done as a simple ratio/proportion calculation or as a calculus solution by differentiation.
If this is not clear, a course in college physics may be helpful.
Good luck.|||i just wanted to let you know that on a helicoptor you have to balance the rotor blades as well as put then in track with one another. if this is not done you will not be able to control the aircraft. this can be a difficult task if you dont have the right equipment so before tring to fly keep this in mind and good luck. if you would like a more in depth answer feel free to contact me. i did this for 8 years on all types of helicoptor.|||Damn aviophage took the words right out of my mouth!
One thing. A fixed-wing aircraft is a heavier-than-air craft where movement of the wings in relation to the aircraft is not used to generate lift. The term is used to distinguish from rotary-wing aircraft(helicopter) or ornithopters, where the movement of the wing surfaces relative to the aircraft generates lift. Fixed-wing aircraft are called airplanes in North America (the U.S. and Canada), and aeroplanes in Commonwealth countries and Ireland (excluding Canada). These terms are derived from Greek
You should study helicopters more and learn about all of the Characteristics.
