“…Modern aerospace vehicles have a limited fuel tank capacity, fly long distances without refueling, and operate at high altitudes at extremely low temperatures. The modernized flying vehicles have accordingly changed the requirements for fuel properties, which have a key influence on an aircraft's flight performance [1][2][3][4][5][6][7]. The most important fuel properties are heating value, density, low freezing point, and viscosity.…”

The paper describes the synthesis of novel strained hydrocarbons based on a diene of the norbornene series, namely 5-methylene-2-norbornene, using catalytic cyclopropanation with diazomethane. The study demonstrated the possibility of selective cyclopropanation solely along the endocyclic double bond. The physicochemical properties of the hydrocarbons were investigated systematically. These hydrocarbons were shown to have an advantageous combination of high density, low freezing point, and high energy density value. The study’s findings indicate that the compounds synthesized are promising as a component of high-energy-density fuels for modern jet engines.

“…At temperatures above 480 • C, the fuel produces deposits mainly by cracking reactions [14]. A large number of researchers have investigated the effects of changes in fuel composition [15,16], dissolved oxygen content [17][18][19], metal surface catalysis [20], fuel polar substances [21][22][23], and fuel flow patterns [24][25][26][27] on the thermal deposition of fuels. The heat transfer deposition of RP-3 includes not only thermal oxidation deposition generated at lower temperatures, but also the thermal cracking deposition generated at higher temperatures.…”

The integration of active cooling systems in super or hypersonic aircraft using endothermic hydrocarbon fuels is considered an effective way to relieve the thermal management issues caused by overheating. When the temperature of aviation kerosene exceeds 150 °C, the oxidation reaction of fuel is accelerated, forming insoluble deposits that could cause safety hazards. This work investigates the deposition characteristic as well as the morphology of the deposits formed by thermal-stressed Chinese RP-3 aviation kerosene. A microchannel heat transfer simulation device is used to simulate the heat transfer process of aviation kerosene under various conditions. The temperature distribution of the reaction tube was monitored by an infrared thermal camera. The properties and morphology of the deposition were analyzed by scanning electron microscopy and Raman spectroscopy. The mass of the deposits was measured using the temperature-programmed oxidation method. It is observed that the deposition of RP-3 is highly related to dissolved oxygen content (DOC) and temperature. When the outlet temperature increased to 527 °C, the fuel underwent violent cracking reactions, and the structure and morphology of deposition were significantly different from those caused by oxidation. Specifically, this study reveals that the structure of the deposits caused by short-to-medium term oxidation are dense, which is different from long-term oxidative deposits.
