"UAVs for Arctic, maritime and border surveillance--and emergency response"

[Colin Parkinson]

I wasn’t clear, I suspected that those factors play a part for both the UAV’s and the jets in the clarity of images. I know from tests we did in the CCG that vibrations effect even stablized optics degrading the range they are useable, more so with digital stablization. Mind you stablized is still better than not!
In a perfect world the mount and airframe are designed to reduce as much vibrations as possible and the stablization deals with the rest and movement caused by flying through the air. As for airspeed I was guessing that higher speeds make it harder to stay focused on the target.

We put high-magnification systems on helicopters, which have way more vibration than anything seized-wing, and the stabilization works just fine.

I operate the MX-20 EO/IR and have 4 Allison T-56 engines with Hamilton Standard props generating vibration that rival that of Loachman's helos. Vibration is hardly an issue.

As for airspeed I was guessing that higher speeds make it harder to stay focused on the target.

I travel through the air considerably faster that my whirlybird-flying brother Loachman and a combination of operator training and modern technology makes that a non-issue as well.

Sounds like we have a competition shaping up - whose vibrations are the most powerful.

In any case, definitely no issue for the systems being vibrated.

Be sure to find the pretty yellow one under applications.

I was attached to the RPV trials in the 80's at Suffield, RPV being what they now call UAV's. The test bed aircraft used a glorified chainsaw motor and video camera was mounted on a ring underneath, crude by today's standards, but it worked mostly, except for the periodic encounters with the ground. We supplied the artillery to fired at the targets using the camera. I have the program insignia around here somewhere I will have to scan it.


Cdn aviator We had cut down Hamilton standard props on our hovercraft, they were designed to work at higher speeds than our hovercraft went, they were not so good in reverse thrust. But they were a lot cheaper than the proper propellers. Also nothing like getting a "re-manufactured propeller assembly" with a blade 3/4 longer than the others, that will cause some vibration as well!

Thanks for the answers.
