JPWILLYS Posted September 23, 2018 Share Posted September 23, 2018 Hello, I would like to know if there are limitations for flight in icing conditions with a FLIR turret under the nose ( like on photo for exemple). Regards Quote Link to comment Share on other sites More sharing options...
hehe Posted September 23, 2018 Share Posted September 23, 2018 I am unaware of any icing limitations, I would have to dig through ops manuals to see but i can say that some models have window heaters that prevent ice build-up that could block the camera.

JPWILLYS Posted September 24, 2018 Author Share Posted September 24, 2018 Thanks a lot for your answer "Hehe". My concern is with potential significant ice accumulation under severe icing conditions and potential flow "disruptions" in front of lower pitots tubes (static pressure error ?) with AoA for exemple.

I have worked many C-130s with FLIR and never seen accumulated ice on them, especially not enough that would alter airflow. Of all the designs, the one you pictured is one of the smaller FLIR designs. Have you seen the MX-25? Huge FLIR, and they are operating that on the C-130J which has dual pitots on both sides of aircraft. Is there a problem you are seeing that you think is caused by ice build-up on FLIR?

Just picking a nit here. Nice pic, though. Don R. Edited September 25, 2018 by DC10FE Spelling, of course! Quote Link to comment Share on other sites More sharing options...

JPWILLYS Posted September 26, 2018 Author Share Posted September 26, 2018 Thank's for the answers. I'am working on a similar project and the FLIR internal heating capacity does not guarantee deicing. Consequently I inquire about this aspect knowing that the lower pitots are behind. Quote Link to comment Share on other sites More sharing options...

I'am working on a similar project and the FLIR internal heating capacity does not guarantee deicing. Consequently I inquire about this aspect knowing that the lower pitots are behind. I don't know that it was ever designed to completely de-ice. I believe the heating is only there to prevent the image from being obstructed. There are plenty of models that have no de-ice or heaters built in and they work fine. I believe the original picture you posted is a model without heating. Do you have access to DTIC? I find a lot of good reports on that site and it might be a good place to look for this. Edited September 26, 2018 by hehe Quote Link to comment Share on other sites More sharing options...
JPWILLYS Posted September 26, 2018 Author Share Posted September 26, 2018 Thanks Hehe. I don't know DTIC ? It's a data base? The picture of FLIR is from google, just to illustrate my question. Quote Link to comment Share on other sites More sharing options...

Is there a certain model of FLIR that you are looking at? Quote Link to comment Share on other sites More sharing options...
JPWILLYS Posted September 28, 2018 Author Share Posted September 28, 2018 Thanks for your answer. I am looking for the type MX/20. Quote Link to comment Share on other sites More sharing options...
