The F-15C/E has shaped the spine folks and Coalition operations within the heart East for over a decade, patrolling the skies over northern and southern Iraq as a part of Operations Northern Watch and Southern Watch. F-15Cs policed the skies for Iraqi airplane working in contravention of no-fly sector agreements, while the F-15E used to be continually shedding guns onto the Iraqi SAM and AAA emplacements that engaged Coalition plane project this challenge.

The components of the aerodynamic forces and moments depending on friction are not always the same as those depending on the pressure as regards their order of magnitude. Investigations show that the influence of friction is more appreciable for flow over long and thin bodies. In practice, it is good to take this influence into account mainly when determining the drag or longitudinal force. When a surface in a flow has a plane area at its tail part (a bottom cut of the fuselage or a blunt trailing edge of a wing), the pressure drag is usually divided into two more components, namely, the pressure drag on a side surface (the nose drag), and the drag due to the pressure on the base cut or section (the base drag).
2) M = Mx My M z = Mx My Mz + + a+ a+ a + + + + We shall consider a moment about an axis to be positive if it tends to turn the craft counterclockwise (when watching the motion from the tip of the moment vector). In accordance with the adopted arrangement of the coordinate axes, a positive moment in Fig. 1 increases the angle of attack, and a negative moment reduces it. The magnitude and direction of the forces and moments at a given airspeed and altitude depend on the orientation of the body relative to the velocity vector V (or if inverted flow is being considered, relative to the direction of the free-stream velocity V(0).
