A simplified model for predicting the propeller-wing interaction

A simplified model for predicting the propeller-wing interaction PurposeThe traditional numerical methods to predict the interaction between the wing and propeller are too complex and time-consuming for computation to a certain extent.

Abstract

PurposeThe traditional numerical methods to predict the interaction between the wing and propeller are too complex and time-consuming for computation to a certain extent. Therefore, they are not applicable for a real-time integrated turboprop aircraft model. This paper aims to present a simplified model capable of high-precision and real-time computing.Design/methodology/approachA wing model based on the lifting line theory coupled with a propeller model based on the strip theory is used to predict the propeller-wing interaction. To meet the requirement of real-time computing, a novel decoupling parameter is presented to replace lifting line model (LLM) applied for wings with a simplified fitting model (FM).FindingsThe comparison between the LLM and the simplified FM demonstrates that the results of the FM have a good agreement with the results of the LLM, which means that the simplified FM has the advantages of both high-accuracy and real-time computation.Practical implicationsAfter simplification, the propeller-wing interaction model is suitable for a real-time integrated turboprop aircraft model.Originality/valueA novel decoupling parameter is presented to replace LLM applied for wings with a simplified FM, which has the advantages of both high-accuracy and real-time computation.
