  TWO-SEAT LIGHT HELICOPTER IS-2 - PROJECT

Features

  • Large, glass cabin with splendid visibility around,
  • Noiseless rotor with new aerodynamic profile and low tip speed,
  • Safety, covered, noiseless tail rotor,
  • Right side of pilot seat (American style).

Application

  • Patrol and disposal flights: police traffic control, board patrolling, monitoring of pipelines and energetical lines, forest observation, pollution seeking,
  • Basic pilot's education and skill training.

Overdone projects tasks

Technical documentation of prototype

  • drawings and calculation documentation (approx. 70%).

Technological processes and assembly jigs of:

  • composite units (main and tile rotor blades, cabin frame, vertical tail),
  • power transmission units (main and tail rotor gear, rotor hub),
  • metal units of structure (framework, tail beam).

Units made (for tests and flight prototype)

  • main and tail rotor gears,
  • main rotor hubs,
  • composite rotor blades,
  • cabin and doors frames, vertical tail.
