Abstract

A találmány tárgya légcsavar (10) amelynél kialakításából adódóan alapátvégi átáramlás meggátőlt. A találmány szerint légcsavarnak (10)agyrésze (12) valamint abból kinyúlóan elhelyezkedő légcsavarlapátjai(14, 15, 16, 17) vannak, és lényege, hőgy a légcsavarlapátőknak (14,15, 16, 17) az agyrésztől (12) távőlabbi végére légcsavar-főrgástengelyre illeszkedő középvőnallal rendelkező, alégcsavarlapátőkkal (14, 15, 16, 17) együttfőrgó gyűrűsrész (25) vanrögzítve. A találmánynak tárgya tővábbá eszköz hagyőmányős kialakításúlégcsavarőkhőz a lapátvégi átáramlás meggátlására, amelynek lényege,hőgy légcsavarlapátvégekre illeszthető kialakítású abrőncsa van. ŕThe subject of the invention is a propeller (10) which, due to its design, has an obstructed flow through the base end. According to the invention, a propeller (10) has a hub (12) and propeller blades (14, 15, 16, 17) extending from it, and the essence is that the propeller blades (14,15, 16, 17) have a propeller at the farthest end from the hub (12) - a ring part (25) with a central line fitting to the turning axis and turning together with propeller vanes (14, 15, 16, 17) is fixed. Furthermore, the subject of the invention is a device for propellers with a traditional design to prevent flow through the tip of the blade, the essence of which is that it has a tire designed to be fitted to the tips of the propeller blades. ŕ
