Abstract
This study describes an integrated framework in which the basic elements of Aerospace Engineering (performance, aerodynamics and structure) and functional elements (suspension, visibility and production) are integrated and considered. In this study, a fully functional rotor system has been fabricated that can be used as one of the training resources for Aeronautical students. For making the rotor system, various parts of the system have been designed on Solidworks and complete mechanism has been simulated with ANSYS. System analysis has been done at various RPM's and Angles of Attack (AOA). In terms of merit the right items have been selected and processed to provide them with the right shape. In terms of the design and implementation, various machines such as gas welding, arc welding, CNC milling and radial machinery have been used. Certain parts such as electric motors, linear actuators and loading cells have been used. All the fabricated components and electric motor, actuator, load cells are then assembled. This rotor system can produce less lift due to high dead weight and low power motor and having some safety issues.
Highlights
Rotor mechanism is the most vital mechanism for any helicopter
A helicopter main rotor or rotor system is the multitude of several rotary rotor blades and a control system that propagates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that obviates aerodynamic drag in forward flight [2]
Rather we focused on designing a basic rotor system taking some basic problems of rotor dynamics into consideration
Summary
Rotor mechanism is the most vital mechanism for any helicopter. Rotor system as a whole helps the helicopter to take off, land and stay still in the air [1]. Shin et al [12] investigated design, manufacturing, and testing of an active twist rotor In another investigation, David et al [13] attempted to design helicopter rotor blades where optimization techniques had been used for placing natural frequencies. The future scope for this study includes the improvement of the basic rotor system but to address it with different complexities and real life problems and finding out and experiment with a more efficient design for hubs and rotor blades. This manuscript contains the full details about our design, modelling, simulation, final output and comparison between theoretical and practical values of generated lift
