  1. Radar and Sensors AIAA 1 Robert Adams Angie Brooks

  2. Defined RADAR • Radio Detection and Ranging • A system that uses radio waves to detect and determine the direction, distance, and/or speed of objects and map them SENSOR • A device that responds to a physical stimulus and transmits a resulting impulse (as for measurement or operating a control)

  3. Radar Altimeter Gives the absolute height of the Plane. Cost ($) Size (in) Weight (lbs) TRA 3000 3,270 1x5x7.6 1.6 TRA 3500 5,920 3x3x6.9 3.25 King KRA 5,875 3x5x11 6.3 (http://www.freeflightsystems.com/prod_radalts.html)

  4. Weather Radar Displays current weather. Cost ($) Size (in) Weight (lbs) RDR-1400C 30k 6x6x11 12 ART 2100 26k 6x4x10 10 (https://www3.bendixking.com) Antenna sizes vary from 10-18 inches depending on need.

  5. Other Types of Radar • AN/APT – Airborne Radar Transmitters • AN/APW – Airborne Flight Control Radars • AN/APX – Airborne Identification Radars • AN/APY – Airborne Surveillance Radars • AN/ALR-67(V)2 Radar Warning Receiver • APQ-181 All-weather Weapons Delivery Radar

  6. Sensors • Position • Pressure • Force • Radar (http://www.honeywell.com/sites/aero/Aircraft_Sensors.htm) Some Examples from Honeywell…

  7. Position • Measures position of Flaps, engine nozzle, landing gear, and pilot input controls. • This device is a Honeywell RVDT weighing in at 1/3 pound.

  8. Pressure • Measures gage, absolute and differential pressures. • Used in bleed air, fuel, engine oil and hydraulic fluid pressures applications. • Weighs about 5 oz without addition of fitting.

  9. Force • Used for pilot input measurements, servo-loop feedback, overload protection and payload measurement. • Weighs 1.75 lbs • Torque sensor weighs about 2 lbs.

  10. Radar Sensor • Informs the pilot that the enemy has radar pointed at them. • An example is the ALR-69. It is a basic fuzz buster for the military. • Has a 3 by 9 in Cathode Ray Tube. • Cost less then $15000 per unit and weighs approximately 42 lbs.
