FlightGear a multi-platform flight Simulator basics

FlightGear is http://www.aliyun.com/zixun/aggregation/29607.html "> free software, a multi-platform flight simulator, which started in 1997. 1997 the first release continued to develop, and in December 2007 released the 1.0.0 version. The main operating systems for the project include Linux,microsoft Windows (Win), Mac OS X,irix, and Solaris, which need to support OpenGL version 1.0. The latest version is the 2.0.0 release of February 25, 2010. The software licensing agreement is the GNU General public License, so it is free software.

Ground learning isn't really flying, but it actually teaches you to be a pilot. However--the following assignments are essential. Finish it carefully.

The function principle of the vacated

The physics of the force of learning in school life has been very well. But some English always eliminates ambiguity--because the writer is not a professional flight knowledge translator ~ ~ ~

Lift lift gravity weight thrust thrust resistance drag

The wing is usually designed to move forward and separate the air to produce an upward thrust, that is, lift, which makes the plane volley.

Gravity is the downward force, and the lift offsets each other, most of which will not be reduced except for fuel-and, of course, the designer wants to lower that value.

Thrust, even if the engine produces the force that makes the plane go forward.

Resistance is the force that hinders movement. The reaction caused by squeezing other substances (air).

The longitudinal axis/long axis longitudinal axis is the symmetrical axis in the center of the aircraft, and the roll tumbling action and the bank side tilt remain unchanged.

The side axis lateral axis is the connection between the ends of the wing.

The vertical axis is the only vertical line between the center of gravity and the plane of the other two axes.

Aileron aileron

The lateral tilting flight controller is located on the rear edge of the main wing. Tilt the necessary, rotate the steering wheel of the direction of the aileron tilt-the wing of the lift drop, the other direction of the aileron tilting-the wing of the lift rise. The horizontal partial force appears because of the lift change, causes the airplane to incline one side.

Elevator Elevator

The elevator is the tail fin. The control plane acts as a aileron to change the lift, but the two wings are tilted in the same direction.

The rear tail of the driving wheel rises upwards, the tail of the machine is lowered, the nose angle increases;

Rudder rudder

Yaw along the vertical axis.

Trim Tab

Offset the outside of the steering wheel force, reduce the driver's burden.

Basic Mechanics

Resistance: A force that is produced as an obstacle by the relative movement of an object. All matter/object has the characteristic of maintaining the state of the original movement (relative static/relative motion, etc.).

Relative: All objects still/motion are relative to other objects.

The decomposition of motion/force: the physical vector is interpreted as a combination of multiple vectors according to trigonometric functions, or the integrated action is interpreted as a single vector.

Lever principle: According to the triangular function of the force decomposition, the change in the long direction of support is small, relatively short support strength. The so-called four-dial is the truth.
