Abstract

The civil aircraft water and waste water system (WWS) provides potable water for passengers on board and disposes the waste water. System freezing will cause loss of system functions and the inability of flights to dispatch; Based on the normal temperature flight test data, this paper proposes the method of equal difference of recovery temperature to obtain the system heating protection area; The power calculation technology of typical component heater is studied by means of numerical calculation. The flight test results show that the research results of this paper can prevent the system from freezing at low temperature, and can guide the design of anti-freezing of the WWS for civil aircraft.
