Aerospace Blockset 3.4

Six Degree of Freedom Variable Mass Missile Airframe

This model simulates a six-degrees-of-freedom variable mass equations of motion with Simulink® and Aerospace Blockset™ software. This model has been color coded to aid in locating Aerospace Blockset blocks. The red blocks are Aerospace Blockset blocks, the orange blocks are subsystems containing additional Aerospace Blockset blocks and the white blocks are Simulink blocks.

The aerodynamic force and moment contributions are zeroed; therefore a standard point mass projectile path, discussed in first year Physics classes, can be seen when simulated. If aerodynamic force and moment contributions are included, this model shows the expected tumbling of an uncontrolled missile.

This model assumes a neutral end burning solid motor for propulsion and includes rudimentary aerodynamics for the missile body. Fin aerodynamics and other fin contribution are neglected.

By extending the simulation time, a Simulink assertion block will fail notifying you of the missile's collision with the ground.
