Continuing Studies of Liquid Propellant Drops in Hot, High-Pressure Environments.

摘要

Drops of LP 1846 have been heated in the gases and flames above burning solid propellants at pressures up to 20 MPa (3000 psi). Semi-quantitative measurements of drop lifetime versus pressure and drip diameter have been made. Although limited by uncertainty in the visualization, these observations show that the trend toward shorter drop lifetime with increasing pressure seen at lower pressures continues in this regime. Visible light emission from the evolved gases and near the drops was recorded during heating under some conditions. Microexplosions of the drops were not observed.
