Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to Department of Defense, Washington Headquarters Services, Directorate for Information Operations and Reports (0704-0188), 1215 Jefferson Davis Highway, Suite 1204, Arlington, VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.

Guidance and Control Design for a Class of Spin-Stabilized Projectiles with a Two-Dimensional Trajectory Correction Fuze

“…So the particular solution is only considered, which is called dynamic equilibrium angle caused by correction control. Define Δ 0 as a particular solution for (16), and…”

“…Swerve response of the spin-stabilized is a key point of the dynamic characteristic to be studied, when control input is added. Ollerenshaw and Costello gave the closeform formulas for the magnitude and phase angle of a projectile excited by a control force in terms of fundamental and pointed out that spin-stabilized projectiles respond out of phase to control-force inputs forward of the center of pressure [16]. Fresconi and Plostins studied various control mechanism strategies for spin-stability projectiles and gave the correction authority under different conditions [17].…”

Thrusters Pairing Guidelines for Trajectory Corrections of Projectiles

“…For nonrolling projectiles, Guidos and Cooper [11] extended the existing analytical theory for quantifying the free-flight motion to include the effect of a simple lateral impulse applied during flight. Ollerenshaw and Costello [12] explained in detail the swerve response of finand spin-stabilized projectiles subjected to a control force. A good understanding of such swerve response is fundamental to implementing the pairing technique presented in the current paper.…”

“…In Eqs. (11) and (12), the initial incidence of the projectile following an impulse thruster detonation of magnitude J and orientation J can be estimated from the ratio of the impulse momentum and the projectile momentum:…”
