Abstract
The Navy has identified a need for a very compact and rugged attitude control system to maintain "nose first" attitude for projectiles that travel outside the atmosphere. This solicitation specifically addresses an attitude control system design sized to provide torque sufficient to rotate a 100 kg projectile with an angular moment of inertia of 4.42 kg m^2, 90 degrees on its pitch axis in 270 seconds and then reduce the pitch rate to the needed reentry rate to a tolerance of 0.3 degrees/second and achieve a zero-degree reentry angle of attack within 3 degrees. The system design must be suitable for gun launch at 12,000 G,s. Quoin has developed a highly effective means of providing attitude control torques with flywheels. We can provide continuous pitch and yaw torque in a spinning vehicle in a very small package. This innovation can be used in future Navy gun and electro magnetic (EM) launched projectiles and in exo-atmospheric missiles. Quoin will demonstrate functionality of Flywheel ACS through analysis and simulation using 3-DOF Simulink models. The simulations will be validated through hardware testing. Perform ACS design studies. We will build and test a single-axis integrating module to demonstrate high torque Flywheel ACS concepts.
