Icing flow tunnel
A college department is engaged in research into the effectiveness of various
methods of aircraft deicing based on the application of anti-icing fluids. The
department has a wind tunnel capable of speeds of up to 80 m/s (Mach 0.28)
supplied by a fan driven by a 10 HP variable speed DC motor. The test section
can be adjusted through a pitch angle of
20
◦
and instrumentation can be
attached to parts and components mounted in this section. The moving air stream
is cooled by means of a refrigerated cooling unit such that airflow temperatures
of between
