Abstract

A reactive pneumohydraulic displacement system is proposed as an inclined launch system for an aircraft. The advantages of the proposed transport system in relation to the known analogs of comparable energy are stated. A complex non-stationary spatial model of the system is presented. The mathematical apparatus for constructing a model is considered. The calculation results are presented in the form of continual mappings of physical fields and integral characteristics of the launch system. The analysis of the starting characteristics for different proportions of equipment – the ratio of water and air. The conclusion is made about the effectiveness of the proposed launch system and the best equipment conditions.

Highlights

  • The high energetics of the oblique launch of aircraft of various classes is highly desirable, and sometimes critical, since it allows obtaining a sufficiently high load on the wing and, ensuring the design aerodynamic quality

  • At first glance, its characteristics satisfy the requirements for systems for launching an aircraft into flight

  • Issues related to the operation of a reactive system in transient modes, which can be accompanied by intense nonlinear wave processes, are usually ignored

Summary

Introduction

The high energetics of the oblique launch of aircraft of various classes is highly desirable, and sometimes critical, since it allows obtaining a sufficiently high load on the wing and, ensuring the design aerodynamic quality. Obtaining alternative technical solutions remains open, the principal analogs have been known for a long time. Such as the popular toy of the 80-s. At first glance, its characteristics satisfy the requirements for systems for launching an aircraft into flight. On the basis of a complex model, the analysis of the dynamic and thrust characteristics of a reactive pneumohydraulic system of a displacement type and the possibility of its use as a system for entering an aircraft into flight from the surface is carried out
