Shen 4T four single vortex axis engine (Lo - Lo 250). In the turbine helicopter in it has a low purchase and maintenance costs, the main uses include police patrols, the vortex coaxial helicopter training, inspections, power line patrol.
It is designed to meet the safety, comfort and ease of maintenance by the police stations around the world welcomed and widely used.
Details:
Shen 4T series of helicopters in the application based on the improvement of the vortex axis light helicopter, the performance is more advanced, more secure, to the single turbine helicopter standards.
Features:
Non-symmetrical airfoil blades;
Increasing the rotor diameter, increasing the propeller disk area;
Continuous and increasing the take-off power;
Increase the allowable torque;
Improve the speed and cruising speed insurmountable;
Increasing the height of the rotor to enhance skid clear height from the ground;
Parts live longer;
Advanced rotor systems.
Performance:
Shen 4T with Roll Royce Allison 250-C20W turboshaft engines, the engine has more than 8500 million flight hours record, in the 269 series of helicopters also have more than 20 million flight hours record.
The rotor system is the application of advanced performance to win the secret of 4T.
Its payload increased by 30% to take off the weight of a typical mission, its cruising speed of up to 192 km / h and a range of more than 3.5 hours, a ground effect hover height of about 2,400 meters.
Shen 4T manipulation is simple, easy to master. Unique body shape and the large vertical tail surface and the horizontal stabilizer to ensure the perfect combination of flying stability.
Less rigid control system to ensure that the manipulation of control force and high precision, eliminating the installation of hydraulic power systems and the cost control system, vice, weight and maintenance problems.
Flying low vibration, cabin noise, ergonomic design to reduce pilot fatigue seat. Shen 4T make driving comfortable and pleasant flight.
Uses:
Shen 4T versatile, flexible operation. Its superior wide-body fuselage designed to meet different needs. Can be used in the administration of justice, pilot training, power line inspections, news gathering, aviation transportation.
4T is the first application approved by the FAA flight control system with three sets of pilot training models.
Cost and Effectiveness:
Shen 4T is the most cost-effective market turboshaft helicopter. The direct use of cost only 70% of similar products, not only that, Shen 4T its outstanding performance and structure to maintain a high added value.
