AURORA 5-A-01 Unmanned helicopter

Leading Technology

Unmanned Helicopter Independently Developed in China
PEFSS could guarantee the safety of UAV during emergency.


PEFSS(Parachute Emergency-response Safety System)
It is known that significant losses or injuries will be caused to  unmanned helicopter,equipment aboard and ground personnel or facilities once the unmanned helicopter crashes down to the ground upon emergency.This is a difficulty that plagues unmanned helicopter industry.AURORA 5-A-01 is designed with unique PEFSS,which could help the unmanned helicopter to land safely upon emergency by rotor braking system and initiating explosives-ejected parachute,avoiding entangling the parachute cords due to violent rotation of rotor.
 
Rotor braking device
The rotor may be out of control if the unmanned helicopter is in an emergency.If it can not be stopped immediately,the parachute will not be opende normally and the cords will be entangled.Furthermore,it's powerful destructive force may cause significant damages to ground persons or facilities. This type of unmanned helicopter adopts the symmetrical designing of braking parts and driving parts to brake the main shaft gear,which reduces torsion and stress centralized on main shaft gear and increases the stability of rotor being slowed down.The braking could be finished in short time and braking speed coule be controlled by adjusting the tightening of braking disk to realize high efficiency braking.
 
H-beam type fuselage structure
The H-beam technology that is used in architecture sector is introduced to unmanned air vehicle area to redesign fuselage structure to use H-beam as structural body and reinforcing beam as supprot to have a high rigidity,simple structure and fewer components,which facilitates fast removal and repairs.Each beam adopts H shapes to further increase lateral rigidity and bending resistance of fuselage structure and reduce fuselage weight and dimensions and then reduce the UAV weight and improve the duration and working efficiency of unmanned air vehicle.
 
Dynamic gravity center balance system
In order to bring the parachutes into full play,this type of UAV is designed with unique tail gas balance system to convert the emission of tail gas into ascending force effectively and the gravity center of UAV could be adjusted to ensure UAV could touch down with head upward to protect the equipment aboard.
 
Forced air-cooling system
The forced air-cooling system uses hatch positioned at upper part of fuselage to compress the downward airflow compressed by high-speed rotor into the fuselage forcibly to directly bring away the heat to realize high efficiency dissipation and the turbo-shaft jet engine inside the fuselage will be cooled down quickly.
 
Independent tail rotor power system
The independent tail rotor power system is provided to help rail rotor to have its own power system.When the main rotor is out of control during flight,the tail rotor still could be used to control the flight attitude.
