Abstract

En rotorbladdemper (48) inkluderer et legeme (58) med en fot (60), en tupp (62), en første kontaktflate (69), en andre kontaktflate (66), en følgende kantflate (68) og en førende kantflate (70). De følgende og førende kantflater (68, 70) strekker seg mellom kontaktflatene (64, 66). Den første kontaktflaten (64), andre kontaktflate (66), den følgende kantflate (68) og den førende kantflate (70) strekker seg alle lengdemessig mellom fot (60) og tupp (62). Legemet (58) omfatter minst én kjøleåpning (82) plassert nær foten (60), som har en diameter som er omtrent lik eller større enn bredden av den følgende kantflate (68) nær tuppen (62). Legemet (58) avsmalner mellom fot (60) og tupp (62) slik at et første tverrsnittsområde nær foten (60) er større enn et andre tverrsnittsområde nær tuppen (62).
