Simulation and Analysis of Propeller Outflow Field
Aerodynamic shape optimization design of propellers based on propeller blade strip theory (vortex theory), CFD numerical computation and multi-island genetic algorithm.
Design of Chord Section Layering for Propeller Blades
ANSYSR was used to analyze the centrifugal force, gravity and aerodynamic force of the blade, calculate the strength, and design the propeller layup.
First Order Antisymmetric Vibration Mode Diagram of Propeller Blades
Rotating machinery is prone to resonance, so the natural frequency of the blade is calculated to ensure that the blade will not undergo resonance damage under the action of rotational excitation force.
Safety Warnings
- Risk of Rotating PartsThe propellers may cause serious injury when spinning at high speeds. Always maintain a safe distance and avoid direct contact with rotating components during operation.
- Prohibition of Overload and Manual Strength TestingThe structural strength of the propellers has undergone comprehensive testing. Do not exceed the specified load limits, and never test their strength by bending them manually. Any damage or loss resulting from improper use will be the sole responsibility of the user.
- Accessory Installation RequirementsEnsure all accessories are securely mounted to prevent safety hazards caused by loose components.
- Pre-Flight Inspection and Replacement GuidelinesConduct a thorough inspection of the propellers before each flight. If cracks, deformation, or other damages are detected, replace them with new ones immediately. Do not operate with faulty propellers.
- Storage Environment RequirementsStore the propellers in an environment free from corrosive substances such as water, sulfur dioxide (SO₂), nitrogen dioxide (NO₂), chlorine (Cl₂), organosilicon, cyano groups, and phenols. Recommended storage conditions: temperature between 0-40°C and humidity below 80%.
- Installation and Fixing InstructionsWhen mounting the propellers to the motor, use anaerobic screw locking glue of medium or higher strength to ensure a secure connection.
- Compliance StatementUse the propellers in strict accordance with local laws and regulations. Military use is strictly prohibited. Any risks or liabilities arising from non-compliant use will be borne by the customer.
