The Large Helicopter is a type of Rotary Wing Aircraft.

Description / Specifications[edit]

The Large Helicopter is a large rotary-wing aircraft designed for the civilian market.

Hull / Suspension[edit]

An enclosed streamlined hull constructed from steel and lightweight materials.

  • Length: 15.5m, Width: 3.8m, Height: 5.8m (including overhead power plant nacelles).
Rotor Diameter: 18.3m.
  • Overall Volume: 342m³ (25.3 dTons).
  • Unloaded Weight: 11,100 kg.

The large helicopter has tandem rotor blades, one mounted forward and one mounted aft. The twin rotors counter-rotate in order to cancel out one another's torque effect.

The overall volume measures the vehicles maximum dimensions less the rotor blades. The enclosed volume of the hull is substantially lower. The rotor blades can be folded to lie along the length of the aircraft when it is being transported.

The undercarriage consists of retractible wheels mounted on a shock-absorbing suspension system.

Power / Transmission[edit]

Two efficient gas turbine power plants using hydrocarbon fuel: each drives a set of rotor blades. The fuel supply is contained within small protected tanks. The power plants are mounted in overhead nacelles located forward and aft, one below each set of rotor blades.

  • The vehicle is noisy.

Performance[edit]

  • Takeoff Run: 0m.
    • Maximum Takeoff Weight: 22,100 kg.
  • Cruise Speed: 230 kph, Top Speed: 270 kph, Stall Speed: 0 kph.
  • Duration: 4.5 hours at Cruise Speed, 3 hours at Top Speed.
  • Maximum Altitude: 6,000m (depending on the local atmosphere type).

Crew[edit]

The body of the vehicle consists of a large enclosed compartment. The crew compartment consist of two seats located within a front part of the compartment: a third crewmember is often carried in the cargo compartment. The seats are fitted with safety harnesses. The vehicle has basic environmental protection (the hull is weatherproof but is not sealed) and is fitted with basic environmental systems and interior lights. Both of the front seats are fitted with mechanical controls. Consoles provide data such as velocity, altitude, and component status.

The vehicle has a large cargo hold accessed by sliding side doors and a rear drop ramp. Cargo may also be suspended below the aircraft on a sling. Some variants are fitted out as passenger transports: it can accommodate a maximum of 32 passengers, though some trade numbers of passengers for more spacious seating.

  • Cargo Storage: 147m³ (10.5 dTons).
  • Maximum load: 11,000 kg (including passengers) before performance is impaired.

Equipment[edit]

Running lights. A small (typically 300 km range) radio communications system, navigation instruments, and a hand-aimed spotlight mounted on the hull base.

History / Background[edit]

A basic rotary wing aircraft (a helicopter) available in a variety of body styles and colors. The density of the local atmosphere dramatically affects vehicle performance.
