"Investigations have been made in flight and in wind tunnels to determine which components of turbojet installations are most critical in icing conditions, and to evaluate several methods of icing protection. From these studies, the requirements necessary for adequate icing protection and the consequent penalties on engine performance can be estimated. Because investigations have indicated that the compressor-inlet screen constitutes the greatest icing hazard and is difficult to protect, complete removal or retraction of the screen upon encountering an icing condition is recommended" (p. 1).

Report presenting a preliminary analytical evaluation of the air and fuel specific-impulse characteristics of magnesium and magnesium-octene-1 slurries. Adiabatic combustion flame temperature, air specific impulse, and fuel-weight specific impulse are given for each fuel.
