Abstract
This paper highlights all the necessary requirements for fabrication and actual fabrication of a
Model Aircraft Cargo Loader. The paper begins with Introduction to Aircraft Cargo Loader along
with aims and objectives of this project. It gives a brief history of freight loaders and the existing
regulations of three different Aviation legislative bodies. The available cargo loaders in market
today are also discussed as a reference for starting the research on how the model under
consideration can be fabricated to perform desired task. Authors have also highlighted any
innovations that can be inducted in the project. The innovations will address the problem of ground
equipment based accidents due to human errors and provide a mechanism for its prevention
during operations.
The paper includes the Industrial Survey and Market Survey to narrow down the resources
required and available in market for construction of the model. The cost and safety factors outlined
from these surveys helped authors in selecting the correct structure and actuator.
The theoretical analysis is carried out to understand the proposed project’s credibility and
components’ specifications that are utilised. It consists of calculations which were carried out to
find the force required to raise 20kg load, torque required to turn power screw for lifting load and
length of power screw required to raise platform to 2ft. height. The design mechanism is also
reviewed through this analysis and its results are utilised to understand the scissor lift’s minimum
angle with respect to base and motor’s power.
Through stress analysis on Ansys, the structural strength and stress involved are simulated. This
analysis was carried out to eliminate any chances of stress failure of model by selecting the correct
materials for model’s components.
Using a 3D model, the project’s proposed design is represented along with step by step assembly
of individual component. The safety systems inducted in model are also discussed in this paper.
Electrical connections and interfacing each electronic component with each other to fulfil system’s
purpose are discussed in detail.
Techniques used during fabrications such as welding, subtractive manufacturing, soldering,
painting, etc. are discussed along with the problem analysis which addresses the troubles faced
during model testing along with solutions used to overcome those problems.
