Standards and Technical Documents - Normal force and pitching moment of conical boat-tails. -- 87033
Description: ESDU 87033 provides an empirical method for predicting the change in normal force and pitching moment due to applying moderate boat-tailing to an axisymmetric forebody-cylinder combination. The method applies for Mach numbers from 0.2 to 5 and angles of attack up to 90 degrees and is derived from
Standards and Technical Documents - Low-speed normal force and pitching moment of slender wings in ground effect. -- 71007
Description: ESDU 71007 provides a simple means of estimating the change in normal force and pitching moment of slender wings at low speeds due to the presence of the ground. The method, which is semi-empirical, applies strictly to pointed slender wings of aspect ratio less than about 2 with an unswept
Standards and Technical Documents - Wing pitching moment at zero lift at subcritical Mach numbers. -- 87001
Description: ESDU 87001 evaluates a simple semi-empirical method by comparing predictions made using it with tunnel data drawn from a wide range of sources. The method determines at low speed the contribution due to the integral of the local zero-lift pitching moments allowing for the effect of taper, and adds
Standards and Technical Documents - Pitching moment derivative due to rate of pitch for projectiles at supersonic speeds. -- 91004
Description: ESDU 91004 gives a semi-empirical method for estimating the derivative for an axisymmetric forebody-cylinder combination with or without boat-tailing and fins. Slender body theory provides an equation for the sum of the pitching moment derivatives due to pitch rate and due to acceleration in heave
Standards and Technical Documents - Pitching moment coefficient increment due to flaps for unswept wings. -- AERO F.08.01.01
Description: Superseded by Item Nos 98009, 98017, 99004, 99014 and 01013. See also Item Nos 97002, 00029 and 03017.
