Here are some 3D models and videos of a few products — or product derivatives — on which I've worked. I used Anim8or
(a very friendly — and free to boot! — program) to create them originally. I've reworked all but one in LightWave 3D.
Note: Left-clicking the links below will access the linked video file. You may have better luck if you right-click on the
link and "Save Target As" onto your PC, then open it from that location.)

Here's a model of a 4-bar linkage, sometimes referred to as a "monkey-motion"
machine. The kinematics of the linkage result in a "virtual" axis above the top of the
vertical arms. This equipment typically mounts inside an RF anechoic chamber with
RF Absorbing Material (RAM), for testing the effects of a radome — the cover over a
radar antenna — on its transmission efficiency.

This is a concept model for a 3-axis radome positioner, along with a 2-axis antenna
positioner, which shares some similarity with the 4-bar linkage, above. This equipment,
also in an RF anechoic chamber, is intended to test both the radome itself and the
radar antenna pattern.

This is a model of a 5-axis Flight Motion Simulator (FMS), configured for an infrared
target scene generator (IRSG). An IR seeker mounts to the innermost (Roll) axis of the
FMS. The IRSG normally mounts to the target azimuth (black) gimbal, and presents a
collimated (far-field) image. In operation, the user programs his simulation computer to
produce a series of Monte Carlo-type flight profiles for a typical target engagement,
and tests the response of the seeker. This allows the user to refine the missile flight
control laws, as well as the seeker/guidance algorithms.

A model of a Radome Boresight Error Measurement System (RBEMS) appears here. In
general, the system includes a Radome Positioner (at the left) and a Null Seeker
Positioner (at the right). The Radome Positioner has both servo-driven and manually-
adjustable axes, making it a very versatile and flexible test element. The Null Seeker
has three servo-driven axes. The entire operation — including RF signal generation
and demodulation, and axis stimulus and data analysis — can be under the control of a
PC. One test scenario determines the precision of the radar pattern and the change of
slope in the antenna pattern, both important for tactical radar applications.
