Measuring of heat flow curves at temperatures near the in-service range have become a standard for stability and compatibility assessments nitrocellulose (NC)-based energetic materials. The typical technique to realise this demand is microcalorimetry. are summarized effect rates all reaction heats in mixture. propellant composition has significant influence on shapes curves. To assess firmer ba...

As the nondestructive testing method based on industrial computerized tomography (ICT) is widely used in solid rocket motor (SRM) propellant defect detection, demand for a corresponding image processing algorithm increasing. In order to extract better information SRM propellants, we studied edge detection their ICT images. This paper proposes guided filter-based images of propellants with much ...

Figure 1 shows the ballistic results for propellants 1, A, and B. The burning rates show no signiŽ cant alteration among the three propellants. The differential scanning calorimetry plots for these three propellants shown in Fig. 2 tell a different story, however. Compared with the baseline, both the carbon and the fullerene soot appear to eliminate the secondaryexothermicpeak at approximately ...

Lift capacity is the key performance of launch vehicle, and high chemical energy bi-propellants are commonly used for modern large liquid rockets. The residual unburned propellant has a strong effect on lift efficiency, especially orbital stages. In this paper, bias control mixture ratio studied, three models, including equal-probability depletion model (EPDM), equal-mass model(EMRM) optimum mo...

The AMPAC-GaTech Partnership fosters research aimed at opening and developing new avenues and compounds that fit the American Pacific Corporation (AMPAC)’s potential market. Under this umbrella, we are exploring advanced propellants technologies (ionic liquids, energetic polymers), azide chemistry, and applied polymers (agriculture, biomedical). The novel catalytic preparation of 5-aromatic sub...

1 Abstract: In the frame of the FAST20XX project under the supervision of ESA, two hybrid rocket engines are developed at Université Libre de Bruxelles (ULB) in collaboration with the Royal Military Academy of Belgium to assess the performance of paraffin/N2O propellants. The goal behind the study is to measure the regression rate and optimize the size of ALPHA, which is a sub-orbital vehicle d...
