D,3. Thermal Property Data and Range of Heat Transfer Coefl&- 

 cients. For purposes of orientation, Table D,3a below lists some 

 thermal properties of typical materials employed in the construction of 

 experimental and practical rocket engine walls. The listed data represent 

 averaged properties between temperatures at ambient and 2000°F, as ob- 

 tained from various sources.

Table D,3b below shows the range of gas heat transfer coefficients 

 /^(BTU/hr/ft^ °F) occurring in various phases of jet propulsion engi- 

 neering.

These ranges of h are based on both experimental data and theoretical 

 calculations.
