An analytical investigation was conducted to predict the rotor wake induced flow velocities along the trajectories of rockets fired from an Army AH-1G helicopter. Three components of both the time-averaged and instantaneous induced velocities were predicted at selected points along the trajectories of rockets fired from four wing locations. Three flight conditions with helicopter flight speeds of 0, 15, and 30 knots were investigated.
