TO THE QUESTION OF AERODYNAMICS HULLS TRANSPORT AND CARGO AIRSHIPS DESIGNED FOR THE FOREST COMPLEX

Abstract

The article touches upon topical issues related to the transport development of forest areas with the help of aircraft, namely aerostatic ones. An assessment of their capabilities and advantages over other modes of transport is given. Examples and technical characteristics of the developed and created experimental samples of hybrid transport-cargo airships, which were intended for operation in the forest complex, are given. The key issue that the authors consider in this article is the aerodynamics of the airship hull, which has a major impact on the movement and maneuverability of the airship in the process of carrying out transport and cargo operations. A simplified method for calculating the flow around the body of an aerostatic aircraft, which depends on the geometric parameters of the body, is presented. The main stages of calculations of aerodynamic parameters are determined, including the transverse and longitudinal flow around the hull, the movement of the aircraft with the angle of attack and the influence of aerodynamic pressure. Attention is paid to the inertial properties of the environment and, as a result, to the method of calculation when moving with acceleration, where the airship is represented by a body of revolution, which is influenced by the attached mass. The presented article is a series of scientific works of the authors aimed at studying the technical parameters of aerostatic aircraft, including aerodynamic performance
