Rob de Bie Posted October 15, 2021 Share Posted October 15, 2021 I've long wondered about the intake color of this CIA U-2. I could not think of a standard 'interior' color that would match it. But maybe it's Corogard? Can anyone comment? Rob Quote Link to post Share on other sites
jonwinn Posted October 15, 2021 Share Posted October 15, 2021 More than likely over spray of fuselage color, a technique commonly used by the U. S. military. The color also almost perfectly matches Kelly Johnson's suit. I believe the intakes of that time frame were like Powers's crashed U2 in Russia, chromate green. jon Quote Link to post Share on other sites
habu2 Posted October 16, 2021 Share Posted October 16, 2021 I cannot imagine a circumstance that would call for the application of Corrogard to an inlet / intake. Quote Link to post Share on other sites
MHaz Posted October 18, 2021 Share Posted October 18, 2021 Most likely that is a dark grey primer that was sprayed on. Most jet intakes are made as smooth as possible in order to not disrupt the airflow headed towards the engine. Jet engines do funny things if the air being pulled in isn't flowing fairly smoothly, so I'd guess it's a sandable primer with dark coloring added. As far as painting is concerned, I would suggest adding a couple drops of black to your favorite match to FS36081 to darken it up and call it good. Quote Link to post Share on other sites
ikar Posted October 19, 2021 Share Posted October 19, 2021 I just noticed for the first time the black nose on that U-2. I have been near a few of them in the pastbut never saw that. I never heard of corogard before.I do remember watching a aircraft mechanic going over a U-2 before a mission and he was not wearinghis shoes. I was curious about this so when everyone left to grab a bite for lunch before teh pilot showed I walked over and saw that the wing had some strange paint on it that actually stood up from the metal. Any ideas what they were using? This was in late 1971 in S.E.A. Quote Link to post Share on other sites
Rob de Bie Posted October 20, 2021 Author Share Posted October 20, 2021 Guys, thanks for replies . Sorry for the late reply, I was away for a few days. jonwinn: yes, overspray is definitely another explanation. habu2: I agree that an inlet duct is not a logical use of Corogurd. MHaz: I would not expect Lockheed to use yet another primer system. In that case I would expect chromate yellow, or chromate green. But Lockheed may reason differently 🙂 ikar: what you describe sounds like the TR-1 that I saw upclose at a Ramstein air show, 1983 or so. To me it looked like very rough sandpaper, 80 or 120 grit. I have no idea what kind of paint it was. Rob Quote Link to post Share on other sites
