Flight of Projectiles

Microspoiler Actuation for Guided Projectiles

The goal of this project was to further mature microspoiler technology to the extent that it could be incorporated into current and future smart weapons designs. Several program objectives, including mechanical design and fabrication, trade study analysis, and limited flight experiments were defined as a collaborative effort between the Georgia Institute of Technology (Georgia Tech) and the Arm...

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

Deceleration of projectiles in sand

Penetration of projectiles was measured for hemispherical and conical nose shapes penetrating granular media. Targets were beds of Ottawa sand and Eglin sand. Projectiles were rigid metals. Experimental parameters that were varied included velocity (from 300 to 600 m/s), nose shape, sand density, and scale (from 5 mm to 20 mm). Strong evidence for scale effects is found: 5 mm diameter projectil...
