Aerodynamic cone stabilizer with cylindrical bearing surface ensures supersonic projectile trajectory stability.
Spiracles in hinged fins vent trapped gases, preventing fin bending at the muzzle brake.
Dynamic trimmable rudders reduce drag from aggressive strakes by decoupling rotational control, extending effective range of gun-fired munitions.
A guidance unit motor rotates within a rigidly attached bearing to shield internal components from inertial loads.
Centrifugal and aerodynamic forces rotate rotatable fins from launch to flight position, eliminating springs or active drive elements.
Nested concentric motors and bearings articulate the nosecone through a central aperture, preserving aerodynamic integrity while transmitting control signals.
A rotatable lock mechanism uses a solenoid actuator to translate rings and bearing balls, locking fin shafts with high stiffness.
