Zwaluw Heavy Transport Helicopter

The Zwaluw (ZWAar LUcht transportWapen) Heavy Transport Helicopter is twin-engine, heavy-lift helicopter of the Knootian Defence Force. Its battlefield-proven 1960s design has been refitted to meet the demands of the 21st century, and it is capable of transporting troops, armoured personnel carriers, light tanks, prefabricated buildings, standard containers or up to 30 tonnes of miscellaneous cargo per trip. One of its variants, the Emergency Medical Service Helicopter, works more akin to a field hospital that can provide critical care for up to seven patients simultaneously.

Design History
One of the oldest helicopter designs to remain in the service of the Knootian Defence Force (KDF), the Heavy Transport Helicopter was originally a fully civilian helicopter, going into production in the spring of 1969 for supply- and lift duties, marketed for heavy industrial applications and the servicing of remote mining outposts in the countries' remaining colonial possessions. Twelve were built and orders were placed for another forty, but decolonisation and the oil crisis and attendant economic problems of the 1970s saw demand for the design slashed. The operating company, Dorestadt Aeronautics, filed for bankruptcy in 1977, leaving the unfinished frameworks for six of its designs to rust at its northern manufacturing plant.

Interest in the Zwaluw was revived in the early 1990s, when the newly reconstituted Knootian Defence Force needed a heavy transport. At the same time, a coalition of parliamentarians and provincial governors from the northern provinces had a keen interest in reviving the Dorestadt Aeronautics yards. An open contest for a transport helicopter contract was heavily slanted towards the Zwaluw's contemporary abilities, and the contract was awarded to Eurocorp BV, which had taken over the domestic intellectual property for the design and promised to source at least two-thirds of the work to northern construction companies. The subsequent design was militarised, adding features such as a forward-facing cannon, protective armour and countermeasures, as well as an improved engine design that was capable of enhancing its lift capabilities even further.

The Emergency Medical Service Helicopter variant was developed in the wake of the Iesus Christi Civil War. Recognising that too many critically injured soldiers died en-route to proper hospital care, the design was stripped of its offensive capabilities and re-utilised as a humanitarian vehicle. Rather than merely serving the a role of medical evacuation, the Emergency Medical Service variant has the staff and instrumentation needed to provide advanced critical care to multiple patients simultaneously.

Storage capacity
The cargo storage is 9,56 meters by 3,29 meters or just over 31 m2 of floor space. This permits the transport of a single standard container or (when transporting cargo to its final destination) the contents of a standard container without the added weight of the storage unit. Able to carry a load of 29,600 kilogram (62,256 lbs), it is used to bring Mobile Container Headquarters into a battle zone as well as being able to carry light tanks and armoured personnel carriers, such as the Adapted Schwerpunkt Armoured Platform (ASAP) and their crews. More commonly it is used for logistical purposes, supplying Forward Operating Bases (FOBs) and Forward Operating Sites behind the immediate front line.

Extendible wide benches and overhead baggage storage permit the transport of one or two platoons of airborne troops and their equipment, comfortably seating 33 without the need for internal modifications. When serving in a medical evacuation role it can use the same configuration to carry 16 stretcher cases and 2 medical personnel. A dual rail track in the floor allows for the quick insertion of a two rows-one row passenger seat set-up, permitting the transport of up to 50 civilian passengers and their personal belongings.

Battlefield Awareness
The platform has been fitted with forward-looking infrared (FLIR), low-light, and remote-camera imaging. An integrated helmet design has the option of using the rotating day/night IIR system and a night time light intensifying system. A Battlefield Management and Navigation computer is installed, allowing interface with the national CAESAR Battlefield Management System. In addition to the LCD multi-functional displays common to a 21st century glass cockpit, there are contact points the crew's PDA's, allowing en-route charging and networking capabilities. CAESAR allows the on-board displays to display and network accurate real-time information not only of friendly forces, but also of hostile forces, terrain conditions and more.

Armament
The military transport variant is armed with a 30mm Dual Feed automatic cannon for self-defence. This versatile and accurate weapon is able to serve both an air-to-air and air-to-ground role and is able to hold 500 high-fragmentation, explosive incendiary, or DU armour-piercing rounds rounds of ammunition, each of which are fed separately to the gun and may be selected during the flight. The free-firing turret allows an aiming range of +15 to -45 in elevation and 120 azimuth.

Mobility
The Zwaluw concept is built for superior lift capacity at the expense of speed and range. A pair of PK4800 Eurocorp Turboshaft engines each provide 4,800 horsepower (3,579 kW) takeoff power and 4,430 horsepower (3,303 kW) maximum continuous power. These gas turbine engines produce shaft power, rather than jet thrust. The turboshaft engine is in turn connected to the rotors via shafts and gearboxes, which provides all motive power for the helicopter. Its traverse rotors remove the need for the entire tail rotor assembly, saving up to 30% of engine power. A compact fuel tank permits a range of 500 kilometres (311 nautical miles) on internal fuel.

Protection
Extensive all-round composite armour and armoured glass installed around the cockpit and cargo areas protect the pilot and the passengers against armour-piercing bullets and projectile fragments and the rotor blades are rated to withstand several hits of ground-based automatic weapons. Additional protection has been built around critical systems such as the fuel tanks, controls, drive system and hydraulics. To counter incoming threats, the transport is fitted with a radar warning receiver, electronic warfare system and chaff and flare dispenser. The dispensers are placed under- and on top of the fuselage. Each casing (container) contains two dispensers with 32 x 26 mm countermeasures each. The whole system works on principle of evaluated response based on infrared or electronic impulse irradiation.

Medical Variant
Rather than merely transporting and stabilising patients while en-route to a medical care facility, the Zwaluw Emergency Medical Service Helicopter can transport seven injured, wounded or sick persons while providing a measure of comfort and access to more advanced care. Stretchers are complemented by amenities such as blankets, sheets, pillows, immobilisation devices, bedpans and a urinal. The physicians have access to portable regulated suction and oxygen supply- and administration equipment, respiratory protection, manual resuscitators, an external defibrillator, pulse oximeters, a variety of bandages and medications that are commonly needed to deal with workplace accidents and battlefield trauma. Staff are equipped to maintain high standards of infection prevention and control, and may be equipped with appropriate CBRNE PPE (chemical, biological, radiological, nuclear, explosive personal protective equipment), including respiratory and body protection.
