Retractable gear
  • To decrease drag in flight undercarriages retract into the wings and/or fuselage with wheels flush with the surrounding surface or concealed behind flush-mounted doors; this is called retractable gear.
  • If the wheels don't retract completely but protrude partially exposed to the airstream, it is called a semi-retractable gear.
  • Most retractable gear is hydraulically operated, though some is electrically operated or even manually operated on very light aircraft.
  • The landing gear is stowed in a compartment called a wheel well.
TAPAS UAV
  • TAPAS is Tactical Airborne Platform for Aerial Surveillance beyond horizon. It is also known as RUSTOM-2.
  • It was developed by India on the lines of American Predator Drones. The first flight of TAPAS took place in 2016.
