HEATING SYSTEM FOR AIRCRAFT ENGINE LIQUID DISTRIBUTION SYSTEM

A heating system for heating a component (48a) in a liquid distribution system (20) of an aircraft engine. The liquid distribution system (20) feeds a liquid to the component (48a). The heating system includes an acoustic generator (30) disposed in communication with the component (48a) via a liquid passage (46a) of the liquid distribution system (20). The liquid passage (46a) defines a length (L3) between the acoustic generator (30) and the component (48a). The acoustic generator (30) generates a resonant frequency selected as a function of the length (L3) of the liquid passage (46a) to generate a standing wave in the liquid within the liquid passage (46a), the standing wave transmitting energy to the component (48a) to heat the component (48a).
