Opis:
The combustion temperature is one of parameters influencing the efficiency of combustion process. The analytical, model and design calculations of processes related to fuel combustion and heat exchange intensity require the combustion temperature to be correctly determined. These are, however, complex, and, as a consequence, burdensome and time-consuming requirements. Developing an appropriate software program will considerably streamline the calculation procedure. Based on analytical relationships for the combustion process, a computational software program has been developed within this study, which enables the determination of the calorimetric, theoretical and actual combustion temperatures of solid fuels.

Opis:
Different kinds of solid composite propellant (SCP) are described. All ways to increase energetic potential of SCP are considered as well as pro et contra of each of these ways. Different kinds of oxidizer (perchlorates of ammonium, hydroxylammonium, and hydrazinium; ammonium salt of dinitramine; other saltlike and molecular oxidizers) are under consideration. The main principles creation of SCP formulation with optimal characteristics in the context of their concrete purpose are discussed, e.g. for rockets with considerably low ratio propellant volume/empty construction mass (V/M lower than 1 Litr/kg or so) the ballistic effectiveness may be increased with the replacement of aluminum by high-dense zirconium or zirconium hydride. Possibilities for creation of special SCP formulations for application at the far space, e.g. for Mars exploration are discussed as well.

Opis:
The basis of basic research consists in the influence monitoring of unconventional (extremely low temperatures) charging intercooling on the selected ecological and economical parameters of a turbocharged internal combustion engine in the specific operational conditions (periodic starts and stops). The paper deals with the influence of the mentioned temperatures from the point of view of the harmful gaseous emissions production withfocus on NOx. The theoretical analysis, consequential mathematical modelling (in Fluent) of the utilizing of the extremely low temperatures of charging after the intercooler in the range from 30°C to near above zero temperatures of the turbocharged engine should define the changes trends in its power parameters and exhaust gas emissions production mostly NOx. At the same time it should consider the influence of the extremely low temperatures of charging on the engine inner corrosion at the periodic engine starts and stops. The mathematical model should allow alternatively solving possible risks resulting from the proposal newness and originality. From the proposal it is expected to obtain more effective energy utilization, the decrease of the environment ecological load compared with the standard solution and the possibility of creation of the permanent sustainable energetic system. The possibilities of the design solution for the system of extremely low temperatures of air fuel mixture are also presented in the paper.
