Factors Affecting Characteristic Length of the Combustion Chamber of Liquid Propellant Rocket Engines

Mehran University Research Journal of Engineering and Technology, 2019
Optimum characteristic length of the combustion chamber of liquid rocket engine is very important to get higher energy from the liquid propellants. Characteristic length is defined by the time required for complete burning of fuel.

Coupled Lagrangian impingement spray model for doublet impinging injectors under liquid rocket engine operating conditions

, 2017
To predict the effect of the liquid rocket engine combustion chamber conditions on the impingement spray, the conventional uncoupled spray model for impinging injectors is extended by considering the coupling of the jet impingement process and the ...

Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re‐entry rates, emitting pollutants throughout the atmosphere. The environmental impact of SMCs lacks characterization to determine the need for regulation. We utilize a global 3D emission inventory of recent (2020–2022) space activity that distinguishes SMC ...

The Role of Propellant Type, Re‐Entry, and Plume Reactions in the Atmospheric Impacts of Spaceflight

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract The space industry is growing rapidly, and over the coming years the number of annual rocket launches is expected to increase further. This increases the sector's emissions and environmental effects, both of which are not yet comprehensively understood.

Microspherules formed by lightning strikes

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 743-767, May 2026.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Anti‐Astrotropik — Outer space, technology and resistance in the tropics

Singapore Journal of Tropical Geography, Volume 47, Issue 2, Page 289-316, May 2026.
This paper traces an intellectual and geographical arc of thinking about outer space in the tropics, connecting Peter Redfield's Space in the Tropics: From Convicts to Rockets in French Guiana (2000), Sean T. Mitchell's Constellations of Inequality: Space, Race, and Utopia in Brazil (2017) and Asif Siddiqi's Cosmic Fragments: Dislocation and Discontent
