Designs of multi-spacecraft swarms for the deflection of apophis by solar sublimation [PDF]

open access: yes, 2009
This paper presents two conceptual designs of multi-spacecraft swarms used for deflecting Apophis. Each spacecraft is equipped with a solar concentrator assembly, which focuses the solar light, and a beaming system that projects a beam of light onto the ...

Sublimation enthalpies of organic compounds by isothermal thermogravimetry

open access: yesJournal of Thermal Analysis and Calorimetry
Abstract An improved method has been developed to determine the sublimation enthalpies of solid organic compounds using thermogravimetric analysis and applying an isothermal methodology with a TA Instruments® SDTQ600 equipment. This was achieved by measuring the rate of mass loss as a function of the temperature from isothermal experiments in

The rate of water vapor evaporation from ice substrates in the presence of HCl and HBr: implications for the lifetime of atmospheric ice particles [PDF]

open access: yesAtmospheric Chemistry and Physics, 2003
Using a multidiagnostic approach the rate Rev [ molec cm-3 s-1] or flux Jev [ molec cm-2 s-1] of evaporation of H2O and its corresponding rate constant for condensation, kcond [s-1 ], on a 1 µm thick ice film have been studied in the temperature ...

Theoretical and experimental investigation of the destruction of graphites in a flow of dissociated air [PDF]

open access: yes
A method is presented for calculating the heating and erosion of blunt bodies made of graphite in a high-enthalpy flow of dissociated air, assuming chemical equilibrium on the surface and taking account of the thermal effects of combustion and ...
