Leading edge erosion Leading edge erosion nabs (Aeronautics) (OP) 17 Nov 02 04:59 Does anyone know of any anti erosion products that could be applied to the leading edge of main and tail rotors blades. RE: Leading edge erosion radomir (Aeronautics) 20 Nov 02 03:34 Usually anti-erosion strips are bonded to the leading edges. They are made of Titanium sheet less than 0.040 inch (1 mm) thick. RE: Leading edge erosion helimaverick (Aerospace) 2 Dec 02 22:31 there is a product called ceram-kote that has been used on the leading edges of blades in some military applications. i've used it on some internal applications and it seems to work pretty well. RE: Leading edge erosion dave081069 (Aeronautics) 3 Dec 02 00:18 3M manufacture a range of polyurethane protective tapes, however these are mainly intended for wing leading edges and radomes so may not last on rotor blades. Could be a budget option though? RE: Leading edge erosion jburr737 (Aeronautics) 21 Feb 03 16:52 Prop-Guard is a distributor of a product that attaches to the leading edge of aircraft propellers. It is made from a polyurethane protective laminate which works well if not intended for seaplane for helicopter use. RE: Leading edge erosion Tads (Aerospace) 9 Apr 03 18:56 Hey, don't use those fixed wing products! Prop and fixed wing leading edge erosion tapes disbond in helicopter applications. Very different environments, and you'll get into a whole bunch of troubles: disbonding, vib, balancing problems, etc...We just use nickel steel erosion strips on the LE, works fine. Very rarely replace them. If you're fitting them to a blade that doesn't have them, there may be an existing STC you can use for that blade - worth a look.

It will work (no vibration or strap lost) RE: Leading edge erosion htk161sw (Aerospace) 26 Dec 03 14:59 The U.S. Army has sponsored many research contracts on the erosion protection of helicopter rotor blades since the end of Desert Storm war. Most of the research has been conducted by Hontek Corporation of South Windsor, CT. The company has also done work for the U.S. Navy, and the Air Force. They have developed a series of extremely erosion resistant molding resins and sprayable coatings. You can write to firstname.lastname@example.org for further info. RE: Leading edge erosion klyde (Electrical) 24 Jan 04 21:05 I'm using a leading edge tape from A/C Spruce on a composite rotor spining at 500rpm with a 25' diameter. The tape is a 3M tape that states that it is not for propellors or helicopter rotors. I have 100 hrs on it in the desert environment and so far so good. I tried SS tape but it didn't hold up in the rain or provide any longevity. It seem to start oozing down the blade with centrifugal force and cause wrinkles in the tape. RE: Leading edge erosion Peter7307 (Structural) 25 Jan 04 04:31 nabs,I pass this on for what it is worth.It cam up on another board for MG sports cars where the question of fitting a fibreglass hardtop was being discussed."RichYou might try using some clear chafe tape, 3M makes some p/n 8671. Its kind of expensive, you might go to an airport to get some. Its used on helicopters and is called blade tape. Maybe they will sell you just a lenght that you need.Philip "Regards, Pete.
