“…Currently, no engine by itself is capable of providing both a high Thrust to Weight Ratio (TWR) and a large specific impulse across the entire Mach range (Murthy and Curran, 1991;Daines and Segal, 1998). As shown in Figure 1 (Zhangtian et al, 2019), airbreathing motors have a good specific impulse but are only functional over a limited Mach range. In contrast, rocket engines have the best TWR but a very low specific impulse over the entire Mach range.…”

This study investigates the feasibility and performance of a missile propelled by a Hybrid Rocket-Based Combined Cycle (HRBCC) engine, which combines hybrid rocket and air-breathing engines. The HRBCC engine could enable intra and extra-atmospheric hypersonic flight in the future. Using a hybrid rocket engine could bring several advantages as reduced costs, increased reliability and simplicity. This research presents the unique feature of the hybrid rocket engine developed by HyPrSpace and explains its benefits for the conception of a HRBCC system. The performance of the missile was studied in two operational modes: pure rocket and ramjet. The results were then used to develop an in-house code that compared the trajectory of different missiles. Our findings indicate that HRBCC engines provide several advantages over other propulsive technologies and can meet the requirements of various military applications.

“…RDE is considered as one of the most promising aerospace power devices, because it is simply structured and a single ignition provides a sustained thrust in its compact combustor. In addition, it is possible to build combined-cycle RDE (Wolański, 2011;Zhang TT et al, 2019). The practical application of RDEs has attracted significant research interest since the 1960s, shortly after Voitsekhovskii (1959) achieved short-lived rotating detonation.…”

The relationship between the number of detonation waves and the evolution process of the flow field in a rotating detonation engine was investigated through a numerical analysis. The simulations were based on the Euler equation and a detailed chemical reaction model. In the given engine model, the flow-field evolution became unstable when a single detonation wave was released. New detonation waves formed spontaneously, changing the operational mode from single-wave to four-wave. However, when two or three detonation waves were released, the flow field evolved in a quasi-steady manner. Further study revealed that the newly formed detonation wave resulted from an accelerated chemical reaction on the contact surface between the detonation products and the reactive mixture. To satisfy the stable propagation requirements of detonation waves, we proposed a parameter called NL, which can be compared with the number of detonation waves in the combustor to predict the evolution (quasi-stable or unstable) of the flow field. Finally, we verified the effectiveness of NL in a redesigned engine. This study may assist the operational mode control in rotating detonation engine experiments.

“…Epoxy resins (EP) are widely used in industrial blowers, aircrafts coatings, and rocket engine, due to their excellent mechanical properties, chemical stability, and corrosion resistance [1,2,3,4,5,6]. Especially in the aircraft flying speed below Mach 1.5, EP exhibit superior light weight, corrosion resistance and fatigue resistance compared to other resins [7,8,9,10,11]. Thus, in the coating on A400M and Boeing 787 aircrafts, the epoxy resin matrix accounts for 36% and 50% of the aircraft weight respectively [12].…”

Epoxy resins are essential in aircraft coatings due to their strong mechanical properties and corrosion resistance. However, their limited high-temperature resistance restricts their use in high-speed aircraft, particularly for anti-static and electromagnetic-shielding coatings, which incorporate conductive networks. The dispersion of conductive fillers is hindered by the crosslink network of epoxy resins. Here, we developed a mixture curing system combining diethylenetriamine and dicarboxylic phthalimide. This system allows imide to copolymerize with the epoxy resin, enhancing temperature resistance and optimizing the dispersion of fillers by adjusting the densities of chemical and physical crosslinks. Our results indicate that the decomposition temperature of the epoxy composite increases to 383.8 °C, suitable for aircraft exceeding Mach 3 speeds. Additionally, the percolation threshold for carbon black fillers in this system is 8.1 vol%, significantly lower than the ca. 70% in volume-exclusion systems. This reduction is primarily due to the liberation of epoxy resin segments from the chemical crosslink network. The electrical performance is also notable, with volume resistivity dropping to 0.2 Ω·m near the percolation threshold, meeting anti-static product requirements. This advanced epoxy resin system shows promise for use in electromagnetic coatings on aircraft, given its enhanced temperature resistance, anti-static properties, and mechanical strength.
