Developing of transport airship for delivery oversized cargo to vostochny cosmodrome

An overview of existing methods of delivering oversized cargo using water, rail, road, air and airship transport, an analysis of the world experience in creating lighter-than-air aircraft and identified the most urgent tasks for this type of vehicles in the field of rocket and space technology, in particular, transportation of oversized elements of super-heavy launch vehicles from manufacturers to the Vostochny cosmodrome, search and rescue of astronauts, evacuation of spent stages from fall fields to disposal points and transportation of oversized trusses. The goals and objectives of this work are defined: review of existing projects of transport airships and study of their designs, development of the layout of a transport airship for delivering stages of superheavy launch vehicles from manufacturers to the Vostochny cosmodrome, calculation of the characteristics of the main systems and detailing the design of the vehicle. As exceptional design solutions, we tested the power scheme of gas shells based on supercharged spiral pneumatic structures that allow you to thermostat the carrier gas and fold the shell for storage, as well as a tangential system for blowing the aerodynamic shell, which allows you to reduce the drag of the device. Based on the developed layout, a simplified mathematical model of the device was created, which allows determining the optimal design parameters. These parameters were used for detailed development of each of the systems, then iterative calculation was performed. As a result, the design of a transport airship for the delivery of oversized elements from manufacturers to the Vostochny cosmodrome was developed and its main technical parameters were determined: load capacity-100 tons, cruising speed-126 km / h, flight range-10 thousand km.
