how to measure the pressure -the antennas pitot
The man is a being designed to move on the ground and usually at low speed, is totally unable to appreciate some characteristics with this, an instrumentation adapted to control the parameters necessary for the conduct and control of an aircraft
1.1. GOAL:
• Indicate the movement of the aircraft;• Helping the driver to keep his plane in a definite flight;
• Contribute to the safety out of blind flight.
1.2. SIZE CHARACTERISTICS OF FLIGHT RULES:
These quantities are:
• altitude;
• The vertical speed;
• The airspeed.
2. PRESSURE DIFFERENT
2.1. DEFINITION OF DIFFERENT PRESSURES
2.1.1. STATIC PRESSURE TRUE:
This is the pressure prevailing at the place where the aircraft in the absence of any movement thereof is.
2.1.2. STATIC PRESSURE:
Is the atmospheric pressure at the flight.
It must be taken into permanent flow areas by lead a probe perpendicular to the airstreams, it is near the PSV.
2.1.3. GAP PRESSURE
This is the difference between PSV and PS: DPS: pressure difference.
2.1.4. DYNAMIC PRESSURE
It is due to the kinetic energy acquired by the air in contact with the probe Pd = 1 / 2ρV2
2.1.5. TOTAL PRESSURE
It is the sum of and is taken from a continuing flow area by a probe lead parallel with the airstreams.
3. PRESENTATION OF THE TUBE PITOT:
It is up to:
• A levy ;
• A water discharge system;
• A heating element.
