baffle
- Definição1
- (1) A series of partitions in a fuel tank to control the rapid flow of fuel and prevent its sloshing. These partitions have holes that allow the fuel to feed to the tank outlet, but they keep the fuel form surging enough to uncover the fuel outlet. (2) A partition separating the upper portion of the tank that prevents oil pump cavitation as oil tends to rush to the top of the tank during deceleration periods. The baffle is fitted with a weighted swirl outlet control valve that is free to swing below the baffle. The vale closes when oil at the bottom of the tank rushes up when the aircraft decelerates. (3) A sheep metal shield used to direct the flow of air between and around the cylinders of an air-cooled reciprocating engine. (4) A partial partition in the pitot system to trap moisture and any solid matter as well as to reduce turbulence.
