The Sikorsky S-76D SAR helicopter (search and rescue) is based on the S76D helicopter, the latest member of the S76 helicopter family produced by Sikorsky Aircraft. The helicopter is for the missions of SAR, homeland security, and airborne law enforcement.
The Sikorsky S-76D helicopter made its maiden flight in February 2009. The helicopter received a type certificate from the Federal Aviation Administration (FAA) in October 2012. The Japanese Coast Guard (JCG) awarded three contracts for a total of 11 SAR Sikorsky s-76 helicopters between 2012 and 2013.
The first helicopter is expected to be operational with the JCG in 2014. The Rescue and Rescue office of the Chinese Ministry of Transport (MOT) signed a contract with Sikorsky for four Sikorsky s 76d SAR helicopters in March 2013. The contract also involves an option for four additional helicopters.
SAR Sikorsky S-76D Dimensions and Designs
The Sikorsky S-76D composite airframe consists of fully composite main rotor blades and retractable landing gear. The new tail rotor blade design and dual-speed wing rotor system meet quiet aircraft standards capability. The helicopter has a total length of 16 m and a height of 2.45 m. The diameter of the rotor is 13.4m. The maximum gross take-off weight is 5.306 kg. The helicopter could carry a load of 2,037 kg.
SAR Sikorsky S-76D Cockpit and Avionics
The Sikorsky S-76D’s state-of-the-art cockpit can accommodate two crew members, including a pilot and a co-pilot. Thales’s fully integrated glass cockpit features a redesigned instrument panel that combines a Thales TopDeck helicopter avionics suite with four large-format liquid crystal displays (LCDs). The cockpit is compatible with the use of night vision goggles (NVG).
Flat-panel LCD screens can display an indicator for altitude, navigation, map, flight characteristics, and other functional management factors: intuitive screens and an easy-to-use interface provide better situational awareness for the crew while reducing workload. The avionics suite also involves a four-axis autopilot, Collins Dual navigation/communication Pro Line 21, the Goodrich Vigor and health and usage monitoring system, HUMS, and the Honeywell Primus 660 weather radar system.
The solid-state aircraft data system provides cockpit data, which uses a dual-trimmed heading reference system, AHRS, and a dual air data computer.
The Sikorsky S-76D helicopter is compatible with IFR (Single Pilot Instrument Flight Rule) operations. Transmitter (ELT) to improve the safety of the helicopter. The helicopter can be optionally comes with a traffic and collision warning system and TCAS1.
S76D Deluxe Helicopter: Better Quality
This is an important improvement over the previous C ++ model and aims to improve performance significantly. For example, this model should have higher and hotter lifting capacities. It will be able to lift about 1,000 pounds more than the previous model. This additional capacity is due to the improved PW210S engines used by the company. In addition, the new composite main rotor blade would also contribute to this additional capacity.
Along with these features, the S76D also has a new cockpit design and a new vibration control system. These features will make the pilot and crew a much smoother and safer ride.
Sikorsky S-76D Features:
Some of the Features of Skirosky Include the following:
SAR Sikorsky S-76D Engines
Although two Pratt and Whitney Canada power the S76D SAR helicopter. PW210S engines also come with two Full Authority Digital Engine Controls (FADECs). Every engine develops a maximum power of 1,070 hp.
S76D Search and Rescue Variant Cabin
The S76D helicopter features a large rectangular cabin with the flexible workspace required for search and rescue missions. The cabin crew can be quickly configured to meet the user’s operational requirements. However, it can supplement with different seating arrangements to accommodate four to 12 people.
The observation station installed in the cabin can be occupied by a scene manager or a SAR crew member. It is to manage the data from the day/night imaging sensors. Sliding doors of cabins on either side of the helicopter and rappelling or rapid rappelling kits allow for rapid entry of a tactical team and patient retrieval of waste with ease.
The large cabin offers enough space to integrate special equipment necessary for accomplishing the mission. In fact, the 38-foot luggage compartment onboard the cabin can be modified to suit specific customer assignments.
Rotor blade Compositon
The second most important development of the S76D is using the composite main rotor blade. It is based on the technology used in the third-generation rotor blade of the Comanche RAH66. The composite main rotor blade has a higher tolerance level for damage and wear. In addition, the blade offers greater efficiency in hovering and cruising.
Less noise production
The aircraft also comes with a new tail rotor with extremely low noise levels. The take-off noise level reduces by up to 4 dBA and 1.5 dBA in flight. In addition to the technical characteristics, the S76D also has an aerodynamic body for greater efficiency in transporting larger loads over long distances.
Rotorcraft Icing Protection System RIPS
The S76D also comes with a new Rotorcraft Icing Protection System RIPS. With the help of RIPS technology. Moreover, the boat will be able to operate in freezing conditions, thus increasing the range and functionality of the boat. The main blade and tail rotor blades can be electrically defrosted to minimize power consumption.
The S76D SAR helicopter can fly at a maximum speed of 287 km /h. The maximum ceiling of the helicopter is 3261 m. However, the helicopter reaches a maximum distance of 834 km when flying at a long-distance cruising speed at an altitude of 4000 feet.
439 miles: sikorsky s-76 range
The Sikorsky S92 has a range of 439 miles.
