Effects of Solid‐Fueled Rocket Exhausts on the Stratospheric Ozone Layer

Berichte der Bunsengesellschaft für physikalische Chemie, 1992
AbstractSpace transport systems often use solid‐fuel in boosters and this type of fuel is also very common for sounding rockets. One of the main components in the exhaust is hydrochloric acid. Photochemical model calculations have been performed to investigate local effects after such a rocket launch.

Calculating the spectral density of the radiant intensity of the plumes of solid-fuel rocket engines

, 2012
This paper proposes a model for calculating the characteristics of the radiation of solid-fuel rocket engines (SFREs). The plume of an SFRE is regarded as a gas-dynamic system in which the characteristics of the rocket flight and the distribution ...

90% Hydrogen Peroxide/Polyethylene Solid Fuel Hybrid Rocket Engine [PDF]

41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005
The 90% hydrogen peroxide (HP), concentrated in lab-scale from Japanese domestic production of commercial grade HP, currently regulated below 60% for storing and handling safety have been applied to single perforation polyethylene solid fuel experimental hybrid rocket. Modified 3-way catalyst have been utilized for decomposing the HP.

Content Detection for Continuous and Efficient Production of Solid Rocket Fuel by Peristaltic Mixer

IEEE/SICE International Symposium on System Integration, 2020
In recent years, expectations for low-cost and high-frequency rocket launches for space exploration have increased. Solid fuel rockets are small, inexpensive, and easy to handle.

Analysis of laser backscattering from solid fuel rocket plumes

AIAA Journal, 1991
Analyses have been carried out for a ground-based experiment to measure laser backscattering from solid fuel rocket plumes. Mie scattering theory was used to compute the returned laser power as a function of range, wavelength, and scattering angle. The feasibility of retrieval of plume particle properties through various inversion methods was examined.

Effect of Radiation on the Rate of Burning of Solid Fuel Rocket Propellants

Journal of Applied Physics, 1948
The temperature rise of powder grains in different rocket motors, resulting from the absorption of radiant energy, has been computed by the method of Avery. The calculated results show that more radiant energy is absorbed by the powder grains in large service rockets than in small experimental test motors.

Evaluation of Paraffin–Polyethylene Blends as Novel Solid Fuel for Hybrid Rockets

Journal of Propulsion and Power, 2015
A novel paraffin-based blends fuel prepared from pure paraffin wax of the alkane family with polyethylene of the alkene family is proposed and tested in a slab motor to visualize the droplet entrainment mechanism followed by a hybrid rocket motor test to analyze its combustion characteristics.
