CHIRMA PAJAN .S

Dynamic Assistant Structural Engineer with expertise in structural analysis and design at Bangalore Aircraft Industries Pvt Ltd. Proficient in MSC Nastran and Patran, I excel in optimizing aircraft components for weight and durability. Strong collaborator and problem solver, I ensure compliance with aerospace standards while producing detailed engineering reports.

THEORETICAL PREDICTION AND VALIDATION OF TWO-SEATER AIRCRAFT’S WING FRONT SPAR

The main objective of the spar is to do the hand calculation in an iterative way followed up with the verification of results with FEA analysis. 

AIRCRAFT WING BOX ANALYSIS

 Performed stress analysis on wing box to determine its failure load. Made use of Finite Element Analysis tools to apply distributed load across wing box, ensuring it could withstand maximum operational stresses. Identified critical stress points. 

CYLINDRICAL ANALYSIS

 Calculation of the hoop and longitudinal stresses developed in the cylinder and verifying it FEA results. Performing Stress Analysis by introducing the internal components like frames and longerons, to understand the effect of hoop and longitudinal stresses.

 DESIGN AND FABRICATION OF A PICK AND PLACE ROBOTIC ARM WITH SIX DEGREES OF FREEDOM

The arm has six axes and six degrees of freedom. The six degrees of freedom allow the robot to move in all three dimensions. Six servo motors were used to control the six axes of the robot. The electronic controller is the bridge between the programming software and the robotic arm. Firstly, I performed a kinematic analysis of the model using a software called roboanalyzer. The required torque calculations were done by a software called Roboshop, and appropriate servo motors were selected for the arm. The microcontroller called Arduino Mega is used for sending the commands to the servo motors, and the commands are written in a software called Arduino IDE software.
