Narrow-Body Aircraft

narrow body aircraftNarrow-body aircraft, also known as single-aisle aircraft, are smaller commercial planes with a single aisle running through the cabin. They are typically used for short to medium-haul flights and have a seating capacity of around 100 to 200 passengers. Examples of narrow-body aircraft include the Boeing 737 and Airbus A320 series. The industry is supported by air data test and calibration equipment, mass properties instruments, temperature measurement instruments, torque and force measurement instruments, igniter circuit testers and heat flux sensors & thermocouples to ensure accurate performance measurements, weight distribution, temperature control, and structural integrity.

Physical Properties Systems

Mass properties instruments are used to measure and assess the weight distribution, center of gravity, and moments of inertia of narrow-body aircraft. This information is crucial for ensuring the stability, maneuverability, and overall performance of the aircraft. Mass properties instruments help in optimizing the aircraft’s design, balance, and control characteristics. Products include:

  • Structural Components: fuselage, wings, and tail
  • Aircraft engines: main engines, auxiliary power units (APUs), fan blades, turbine blades
  • Avionics equipment: navigation systems, communication systems
  • Flight control systems
  • Payloads: cargo, passengers, baggage
  • Landing gear: main landing gear, nose gear
