What is tensiometer in aviation?
Cable Tensiometers are hand-held instruments used to measure the tension of a cable. Cables are used in an aircraft to connect the flight controls in the cockpit with the movable parts on the aircraft’s wings and stabilizers, such as the ailerons, elevators and rudder.
How would you use a Pacific T5 tensiometer?
The T5 series cable Tensiometer are standard calibrated on Flexible, wire rope, for aircraft control cables. When using coated cables, select the appropriate size of riser to accommodate the cables increased size. Annotate riser used on the Certification label and/or Calibration Chart.
What is rigging check in aircraft?
Rigging involves setting cable tension, adjusting travel limits of flight controls, and setting travel stops. In addition to the flight controls, rigging is also performed on various components to include engine controls, flight deck controls, and retractable landing gear component parts.
What tools is used in determining tension on a cable?
A dynamometer measures in-line force or tension by means of a load cell or mechanical scale installed between two shackles or hooks. Typically the dynamometer is attached to a ratcheting cable puller on one end and a come-a-long on the other, allowing the cable to tightened while in place as shown in the picture below.
What factors affect cable tension?
Factors affecting the sag
- Conductor weight – Sag of the conductor is directly proportional to its weight.
- Span – Sag is directly proportional to the square of the span length.
- Tension -The sag is inversely proportional to the tension in the conductor.
- Wind – It increases sag in the inclined direction.
How do you measure tension?
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration.
