“…NHOC was measured using the IKA-C6000 isoperibol Package 2/10 Calorimeter according to ASTM D240-02. The specific impulse ( I sp ) was calculated using the rocket propulsion analysis software (RPA Lite Edition v.1.2.9) under the conditions of chamber pressure of 7 MPa, oxidizer excess coefficient of 0.7, and nozzle exit expansion pressure ratio of 70 with liquid oxygen as the oxidizer, for which the formation enthalpy of the fuel was calculated from NHOC. Pressurized differential scanning calorimetry (PDSC) test was implemented using an HP 204 NETZSCH DSC at 2.5 MPa air atmosphere via increasing temperature from 80 to 250 °C in a rate of 10 °C/min.…”

The rapid development of aerospace technology puts forward the urgent needs for fuels with higher energy density and good cryogenic and ignitable properties. Herein, we applied an RCOOZnCH2I-mediated cyclopropanation to synthesize four three-membered cyclic fuels with ca. 100% yield through optimizing the reaction conditions including substituent groups in zinc carbenoids, carbenoid/substrate ratio, and solvents. The fuels show the volumetric heat of combustion to be 3.6–11.7% higher than the currently used fuel JP-10 and low freezing point and viscosity. The advantages of strained fuels with regard to increasing the energy density while maintaining good low-temperature fluid properties are illustrated through comparison with conventional cyclic fuels. Moreover, the strained fuels exhibit low ignition temperature and short ignition delay. This work suggests that the strained fuels are highly promising as advanced high-energy-density fuels.

“…However, they did not report the detailed fuel performances such as low-temperature viscosity and ignitability. Our group synthesized a rocket fuel with a high NHOC of 43.4 MJ/kg and freezing point lower than −70 °C, but the density of this fuel (0.85 g/mL) is still low.…”

“…21 The densities and volumetric NHOCs of terpenes can be further enhanced through cyclopropanation reactions. [22][23][24][25] Isoprene is a compelling substrate for the preparation of sustainable jet fuel blendstocks. It can be directly produced from biomass sugars via fermentation, 26 by dehydration of biosynthetic 3-methyl-3-buten-1-ol, 27 or from other bio-based substrates including mevalonolactone 28,29 and mesaconic/itaconic acid.…”

“…Due to the three strained cyclopropane rings, DMCP has a highly positive enthalpy of formation (979.5 kJ/kg) [6], bringing additional energy into the combustion process, leading to a higher specific impulse than that of petroleum‐derived rocket kerosene. The specific impulse of DMCP reaches 332.2 s, higher than those of U.S. petroleum‐derived rocket kerosene RP‐1 (324.7 s) and high‐density hydrocarbon fuel JP‐10 (323.3 s) [7]. DMCP was used in some upper stages of the Russian Proton launch vehicles to increase payload over that obtainable with petroleum‐derived rocket kerosene.…”

1,2-Dicyclopropyl-1-methyl cyclopropane (DMCP) was found a high-energy liquid hydrocarbon propellant. A model combustion chamber was designed and manufactured to investigate the combustion performance of DMCP and Chinese rocket kerosene (RK) in comparison. Due to the higher density of DMCP, its orifice flow coefficient was 3.4 % larger than that of RK. The chamber pressure fluctuation amplitude of DMCP was within 10 % of the average pressure value. Under typical conditions, the flame intensity of DMCP combustion flame was more intense than that of RK. When the mixture ratios varied from 2.0-2.8, the characteristic velocity changes of DMCP were between 1626 m/s and 1636 m/s. It was not apparent that the characteristic velocity of DMCP was affected by the change of mixture ratio. The combustion efficiency of DMCP increased with the rise of its mixture ratio (varying between 0.902 and 0.921), higher than that of RK in a low mixture ratio. The apparent activation energy values (E) of DMCP were 202.0 kJ • mol À 1 and 202.9 kJ • mol À 1 , respectively, according to Kissinger and Flynn-Wall-Ozawa (FWO) equations.
