Remote Touchscreen-Controlled Defense Turret

Sensitive or intruder-vulnerable areas are, by definition, in need of some form of defense. In such cases, it is potentially desirable to remove human physical presence from the defense, without eliminating human influence. Thus, it was decided that a turret should be made to guard these types of areas, which could be remotely controlled with only simple user input. Due to the variety of potent...

A Vhf-uhf Television Turret Tuner

ITH the advent of ultra-high-frequency television and the subsequent allocation of specific UHF channels, the need for a VHF-UHF television tuner becomes apparent. This tuner should ideally make the maximum use of the same components on VHF and UHF, so that there would be a minimum duplication of parts. This design should be one which would give optimum performance and still be easy to fabricat...

Constrained Predictive Control Of A Servo-Driven Tracking Turret

Vehicle-mounted 2-axis turrets are widely used in high bandwidth tracking systems, frequently encountered in air-to-ground, ground-to-air and air-to-air targeting. Existing controllers for these systems are generally implemented in classical proportional-integral-derivative (PID) form. The objective of this paper is to examine the novel application of constrained model predictive control (MPC) ...

Aero-Optical Environment Around a Conformal-Window Turret

This paper presents the aero-optical environment around a generic conformal-window turret formed from a hemisphere on a short cylindrical base. A suite of optical instruments consisting of a Malley probe, a conventional two-dimensional Shack–Hartmann wave-front sensor, and a new high-bandwidth, lower-resolution Hartmann wave-front sensor were used tomeasure the aberrations on the wave front of ...
