NSA 407MRH Multi-Role Helicopter

Helicopter. The new helicopter was unveiled during the International Defence Exhibition & Conference (IDEX) 2015 held in Abu Dhabi, UAE.

The MRH variant is intended for use by government and military authorities in missions such as light attack, close-air support, intelligence, surveillance and reconnaissance (ISR) / airborne ISR (AISR), utility, cargo, and passenger transport.

NSA 407MRH details

In 2011, NorthStar ordered a total of 56 Bell 407GX helicopters from Bell Helicopter, a subsidiary of Textron, for conversion into MRH version. NorthStar took delivery of the 48th Bell 407GX at Dubai Air Show in November 2015. The unit cost of the NSA 407MRH is estimated to be $9m. The UAE Armed Forces ordered 30 retrofitted MRH helicopters, to be delivered through 2016.

NorthStar signed an agreement with Control and Applications Emirates (CAE) to develop a training solution for the multi-role helicopter variant in February 2015.

Advanced Technology for Enhanced Safety

  • The latest in glass cockpit capability for light helicopters
  • Helicopter Synthetic Vision Technology (HSVT™)
  • Helicopter Terrain Awareness Warning System (HTAWS)
  • Video input for FLIR or other camera display
  • Global connectivity options

Look to the Future with HSVT

HSVT adds increased situational awareness in your rotorcraft cockpit. Using sophisticated graphics modeling, the system recreates a “virtual reality” landscape on your large 10″, 12″ or 15″ primary flight display. This enables you to clearly visualize terrain features, waterways, airport locations, runway depiction and obstacles — even in nighttime conditions.

Avoid Obstacles with HTAWS

An optional HTAWS has been engineered specifically to keep rotorcraft safely separated from hazardous terrain and minimize the chance of CFIT (Controlled Flight into Terrain). The system predicts in advance where potential hazards may lie and alerts you as you near them. A 5-color Terrain Proximity display lets your visualize how close you are to a potential threat while voice callouts audibly announce the helicopter’s height above terrain when descending below 500 feet. For low-level operations, the system even has a Reduced Protection (RP) mode that minimizes alerting while continuing to provide protection.

Satellite Weather and Communication

Keep a watchful eye on weather in the U.S. and Canada with built-in support for our GDL™ 69 satellite datalink, which gives you NEXRAD radar imagery, METARS, TAFS, TFRs, lightning, winds and more through a XM WX Satellite Weather subscription. The GDL 69 can also provide SiriusXM Satellite Radio in the cockpit with a subscription.

When you add a GSR™ 56, you gain global weather capabilities through the Iridium satellite network. It can also support voice, text messaging and flight tracking/position reporting virtually anywhere in the world when coupled with the right subscriptions.

Fly Advanced Avionics

At the core of G1000H, potentially high-maintenance gyro instruments have been replaced with our proven Attitude and Heading Reference System. AHRS takes inputs from GPS, magnetometer and air data computers to achieve unprecedented levels of accuracy. G1000H provides support for Wide Area Augmentation System (WAAS) technology, which offers high-precision GPS guidance.

On the communications side, the 407MRH has military-quality dual integrated tactical ARC-210 multi-band radios, a Terrestrial Trunked radio (TETRA), and a BMS Helicoder 4 microwave video downlink system. Each pilot has a complete control system for the radios, mounted underneath their Garmin 1000H monitor. The helicopter also has an APX-121 Mode IV IFF transponder, plus an L-3 Avionics Systems 3900.2 electronic standby instrumentation system that provides backup airspeed, altitude, and attitude data in a single small display window. (The 407MRH’s tail rotor drive fairing designed by SEA has a built-in shelf for mounting three antennas.)

The 407MRH’s cockpit is night vision goggle-compatible – including the cockpit and console lighting – and is equipped with infrared navigation lights and a dual-mode IR/white light searchlight. To provide protection against hostile fire, the 407MRH has lightweight modular cockpit and cabin armor, plus carbon fiber doors and mission equipment shrouds. “The doors and shrouds were custom-built for Southeast Aerospace for this aircraft,” Rodriguez said. “The carbon fiber doors are 50 percent lighter than the original OEM versions.” Source justhelicopters.com

M134 7.62mm mini gun

The M134D-H Hybrid Gatling Gun is the standard lightweight Minigun design from Dillon Aero. The Hybrid Gatling Gun combines the titanium and skeletonized parts that were originally engineered for use in the M134D-T titanium Gatling Gun with the steel housing of the M134D steel Gatling Gun. The Hybrid gun was designed to offer the weight savings of the titanium gun and the longer service life of the steel gun. The Hybrid system is only two pounds heavier than the original titanium gun, is between 10-20 pounds lighter than the steel system, and has a service life of 1,500,000. The M134D-H is in widespread use in both Crew Served and Fixed Forward applications.

GAU-19 0.50 calibre machine gun

 GECAL-50 / GAU-19/A heavy machine gun is an externally powered weapon of Gatling type. It uses built-in electrical motor to rotate barrel cluster (which has three barrels) and operate feeder-delinker unit. Bolts are cycled through cam-shaped path inside the gun housing, continuously feeding, firing and ejecting spent cases from barrels as they rotate. Gun is fed using standard M9 disintegrating belts, same as used in Browning M2HB heavy machine gun. Since the belt links have closed loops, each cartridge is pulled out of the links by the feeder-delinker unit before presenting it to the gun for loading. Rate of fire is controlled by electronic circuit, and can be adjusted up to 2000 rounds per minute, although GAU-19/B is limited to 1300 rounds per minute due to lighter barrels. GAU-19/A machine guns can be mounted in aircraft gun pods and flexible or fixed aircraft mounts. Surface use includes ring-type mounts installed on the roof of the HMMWV vehicles and pedestal mounts used on naval ships and fast boats. Some types of mounts include integral ammunition containers (with typical capacity between 500 and 1500 rounds) and dedicated battery to operate the gun. Firing controls normally include dual spade grips, attached to the gun cradle, with electric triggers and safety switches.
