“…The studies of combustion of individual structural elements of launch vehicle parts, containers for petroleum products made of combustible materials revealed a number of problems associated with the materials used to make these elements [1,4,5]. In particular, experimental studies of the carbon fiber cladding element used on the PF found that under uniform thermal loading, when the temperature of ⁓ 4000C is reached, burnout of the epoxy binder in the sample is observed, and when ~ 12000C is reached, the carbon fibers of the sample are completely charred and the burnt sample almost completely loses its mass [5]. These experiments were conducted to determine the ignition and combustion temperature of the sample material without taking into account the real operating conditions of the structure (absence of an incoming aerodynamic flow, PF speed on the descent trajectory, and no heating time restrictions).…”

The description of experimental benches for combustion of demonstration elements of material samples - combustion demonstrators (CD) is given. CD for investigating thermodynamic processes during combustion on experimental benches are developed. The results of experimental studies of combustion of CD made of different materials (existing and synthesized) are presented. A new direction of research is formulated - the development of combustible materials and structures made of them, providing the specified characteristics at all stages of operation.

“…Several researchers have proposed panel plate materials combined with fiber and proposed-of-the-art composites that have existed in aviation and rockets (Vavilov et al, 2016;Monogarov et al, 2018). In several areas, the honeycomb materials, from packaging in the shape of a paper carton to sports equipment such as skis and snowboards (Mou et al, 2014), were developed with varied tailored hierarchical honeycomb cores (Li et al, 2020).…”

The honeycomb sandwich structure has been extensively investigated for its mechanical performance. Modification in improving such mechanical properties is an innovation required for honeycomb sandwiches, especially by adding a random fibers reinforcement inside a sheet panel plate. This study was developed random fiber reinforcement using natural fiber of Oil Palm, Sugar Cane, and Coconut, which constructed by the commercial software code of MATLAB. This investigation analyzed the performance of three-point bending behavior using the finite-element model, which provides four levels of fiber condition to observed: 0, 50, 100, and 150 fiber numbers. Ansys Workbench/Dynamic code was chosen to predict mechanical performance such as stress and displacement analysis. In the fiber development study, a series of numerical simulations were carried out with two types of fiber orientation reinforcement, unidirectional and chopped randomly. The hybrid orientation was also implemented in this research by combining unidirectional and chopped fiber, which was fixed at 150 numbers and then varied in three sets: S50/C100, S100:C50, and S75/C75. As a result, it was confirmed that the fiber reinforcement enhances the stiffness of the structure, which contributed a lot to the promotion of the bending resistance capacity and energy absorption. Especially, unidirectional fiber orientation has shown a significant increase in absorbing stress during testing. The fiber reinforcement sandwich demonstrated better mechanical behavior in the simulation, as reported by the hybrid system, and this was influenced by the unidirectional orientation.

“…Recently, studies on the use of plastic as the main structural material for individual rocket elements have been carried out (Monogarov et al, 2018;Trushlyakov et al, 2019), which is conducive to the destruction of detachable parts at re-entry into the atmosphere. Such an approach is extremely important from the point of view of reducing the anthropogenic pollution of outer space (Dron et al, 2019;Alpatov et al, 2020).…”

Purpose Leading developers and providers in the modern space launch market note a splash in the development of ultralight launch vehicle (LV), driven by the growing demand for small satellites for large constellations in low Earth orbits. One of the promising ways to solve the problem of the quick launch of such satellites is to use a new type of ultralight launch vehicle with a plastic body. The project of such a launch vehicle was proposed by Oles Honchar Dnipro National University (Ukraine). Along with that, there is a need for appropriate research studies on the thermal resistance of the plastic shell, as the physical, mechanical and thermophysical characteristics of polymers significantly differ from traditional aerospace materials. The purpose of this study is to validate the design and ballistic parameters of such a launch vehicle in terms of providing an acceptable thermal environment at the atmospheric phase of the trajectory. Design/methodology/approach The workability of a new type of propulsion system is being investigated experimentally in bench conditions. To study the process of aerodynamic heating of a plastic shell, numerical modeling based on the integration of the flight dynamics and heat transfer equations is used. Findings Brief information about the design of a new type of ultra-light autophage launch vehicle with a plastic body is presented. A mathematical model for the movement of the launch vehicle at the atmospheric phase of the trajectory, and for the heating of the polyethylene body of the launch vehicle, taking into account the dynamic change in the atmospheric parameters is proposed. The influence of the motion trajectory on the thermal environment of the rocket body is investigated, rational motion trajectories and corresponding permissible g-loads are determined. Originality/value The fundamental possibility of using plastic (polyethylene) as a structural material and fuel for bodies of a new type of ultralight launch vehicles has been substantiated. It is shown that to ensure acceptable thermal conditions of a plastic body, it is necessary to use thermal insulation. It is proposed to use a polymeric Teflon coating as such thermal insulation. The results are important for the development of technologies for launching small satellites into orbit, as the use of plastic as the main structural material of the rocket body will significantly reduce the launch cost.
