What is Ram rise?
Difference between static air temp and total air temp.
What temperature probe experienced position and instrument error?
Direct reading
What temperature probe has a sensor inside to protect from sunlight?
Indirect probe
How are temperature probes protected by icing?
Electrical heating.
What does a Wheatstone bridge do?
Measure temperature by change in resistance.
How does a thermocouple work?
Voltage proportional to temperature change.
In a thermo couple, what dont we need?
A power supply.
How does pyrometry work to measure tempurature?
EM radiation.
On a TAT probe, what is it made of?
Nickel plated beryllium-copper.
RAM RISE = TAT - BLANK
SAT
Measured ram rise = blank x blank
Ram rise x Recovery factor
SAT = blank - blank
RAT - measured RAM rise
RAM RISE = (BLANK/BLANK)*2
