Within which temperature range will propane fuel vaporize sufficiently for burner operation during flight if ample fuel is available?

Propane is a versatile fuel that requires specific temperature conditions to vaporize effectively for burner operation. The temperature range of 30°F to 90°F is optimal for propane vaporization. At temperatures within this range, propane can easily transition from its liquid state to a gaseous state, ensuring a consistent and reliable fuel supply for burner operation during flight.

If the temperature falls below 30°F, the vapor pressure of propane may become too low for effective operation, potentially leading to insufficient vapor for the burners. Conversely, while temperatures above 90°F can also support vaporization, they may risk other operational issues such as increased pressure in fuel lines and storage tanks. Therefore, the 30°F to 90°F range allows for effective vaporization while maintaining safety and operational efficiency in using propane as a fuel source in lighter-than-air craft.
