Analysis of the feasibility of using a rotary propfan for thrust reversal

Analysis of the feasibility of using a rotary propfan for thrust reversal

Abstract

The paper considers the possibility of using a ducted propfan with a significant rotation of the blade of the rotor fan impeller to change the direction of the thrust vector. Mathematical modeling of the ducted propfan was carried out using a numerical experiment. The gas-dynamic analysis of the propfan parameters was carried out by solving the system of averaged Navier-Stokes equations using the k-ε turbulence model in the ANSYS CFX software environment. The mesh is created in ICEM and has a block structure. Mesh topology takes into account the specifics of the flow calculation in the boundary layer. CFD results are presented - simulation of ducted propfan operation in mode H=0 m, M=0.2. В роботі розглядається можливість використання закапотованого гвинтовентилятору зі значним поворотом лопаті робочого колеса гвинтовентилятору для зміни напрямку вектору тяги. Математичне моделювання закапотованого гвинтовентилятора проводилися за допомогою чисельного експерименту. Газодинамічний аналіз параметрів гвинтовентилятора здійснювався шляхом розв'язання системи осереднених рівнянь Нав’є-Стокса з використанням моделі турбулентності k-ε в програмному середовищі ANSYS CFX. Сіткова модель створена в ICEM і має блочну структуру. Топологія сітки враховує специфіку розрахунку течії в примежовому шарі. Представлені результати CFD - моделювання роботи закапотованого гвинтовентилятору на режимі H=0 м, М=0.2.
