“…In the approximate reaction, the chemical reaction of LOX and RP‐1 can produce the dominant products of carbon dioxide and water vapor (Ebbing & Gammon, ). When it comes to the RP‐1 quasi‐global combustion kinetics mechanism, the listed quasi‐products are CO, H, H 2 , O, OH, and O 2 (Wang, ). Mendillo et al () reported ionospheric TEC depletions due to the launch of NASA's Skylab.…”

The launch of SpaceX Falcon 9 rocket delivered Taiwan's FORMOSAT‐5 satellite to orbit from Vandenberg Air Force Base in California at 18:51:00 UT on 24 August 2017. To facilitate the delivery of FORMOSAT‐5 to its mission orbit altitude of ~720 km, the Falcon 9 made a steep initial ascent. During the launch, the supersonic rocket induced gigantic circular shock acoustic waves (SAWs) in total electron content (TEC) over the western United States beginning approximately 5 min after the liftoff. The circular SAWs emanated outward with ~20 min duration, horizontal phase velocities of ~629–726 m/s, horizontal wavelengths of ~390–450 km, and period of ~10.28 ± 1 min. This is the largest rocket‐induced circular SAWs on record, extending approximately 114–128°W in longitude and 26–39°N in latitude (~1,500 km in diameter), and was due to the unique, nearly vertical attitude of the rocket during orbit insertion. The rocket‐exhaust plume subsequently created a large‐scale ionospheric plasma hole (~900 km in diameter) with 10–70% TEC depletions in comparison with the reference days. While the circular SAWs, with a relatively small amplitude of TEC fluctuations, likely did not introduce range errors into the Global Navigation Satellite Systems navigation and positioning system, the subsequent ionospheric plasma hole, on the other hand, could have caused spatial gradients in the ionospheric plasma potentially leading to a range error of ~1 m.

“…The modeling of JP-8 and other kerosenes is usually achieved using a representative blend of paraffin, naphthene, and aromatic [8,[23][24][25], or by creating a single specie to model the fuel blend [26,27]. For the JP-8 calculations performed using Zhang's model [22], the scheme recommended in the model was used.…”

For hydrocarbon-based fuels to be viable as scramjet fuels they must be able to absorb heat from engine structures in the form of sensible, latent, and chemical enthalpies, while attempting to minimize coke formation. In this study, a short contact time catalytic reactor was used to achieve these ends. Experiments were performed using a series of different catalysts (Pt Al 2 O 3 , Rh Al 2 O 3 , and zeolite) on a set of logistical fuels (JP-7, JP-8, JP-10, and S-8, a synthetic hydrocarbon fuel currently being investigated by the U.S. Air Force). Experiments were performed at low (1-3 atmospheres) and elevated (40-50 atmospheres) pressures, at temperatures of 650 and 750 C. The production of gas-and liquid-phase species was measured as a function of pressure, temperature, residence time, and catalyst formulation. Results show the production of small (H 2 , C 1 C 3 ) species in the gas phase, with a shift from hydrogen and ethylene formation at low pressures toward methane and ethane formation at elevated pressures. In addition, significant coke formation at elevated pressures for all of the fuels was witnessed. Detailed kinetic modeling identified shortcomings in models used for describing the pyrolysis of these fuels.Presented at the 46th AIAA/ASME/SAE/ASEE Joint Propulsion

“…Multiphysics invoked in this effort include turbulence, hydrogen reactions (Wang, 2001) and its associated thermodynamics, convective heat transfer, and surface radiation. The goals of this design are to maintain the 3500 K hot-hydrogen jet as long as possible as it impinges on the sample and to hold the overall chamber wall heat flux below a pre-determined 5 .…”

Abstract. The objective of this effort is to perform design analyses for a non-nuclear hot-hydrogen materials tester, as a first step towards developing efficient and accurate multiphysics, thermo-fluid computational methodology to predict environments for hypothetical solid-core, nuclear thermal engme thrust chamber design and analysis. The computational methodology is based on a multidimensional, finite-volume, turbulent, chemically reacting, thermally radiating, unshucturedgrid, and pressure-based formulation. The multiphysics invoked in this study include hydrogen dissociation kinetics and thermodynamics, turbulent flow, convective, and thermal radiative heat transfers. The goals of the design analyses are to maintain maximum hot-hydrogen jet impingement energy and to minimize chamber wall heating. The results of analyses on three test fixture configurations and the rationale for final selection are presented. The interrogation of physics revealed that reactions of hydrogen dissociation and recombination are highly correlated with local temperature and are necessary for accurate prediction of the hot-hydrogen jet temperature.
