OBJECTIVE:  To list out the total weight of various types of aircraft. To find the difference between ground speed and airspeed. Why is it not recommended to use aircraft engine power to move it on the ground at the Airport? How an aircraft is pushed to the runway when it's ready to take off? To learn about take-off…

AIM: To study the braking characteristics of an Electric Vehicle.   1. For a defined driving cycle, calculate the energy required for braking. It involves the conversion of kinetic energy to thermal energy by applying friction to the moving parts of a system. The friction force resists motion and in turn generates…

AIM: The aim of this challenge is to understand the basics of the powertrain blockset in MATLAB.   What is a Powertrain blockset? A powertrain is an assembly of every component that pushes your vehicle forward. Your car's powertrain creates power from the engine and delivers it to the wheels on the ground. …

AIM: To explore the various functionalities in the 2003 ADVISOR tool of MATLAB.   1. To find whether an electric vehicle with a cargo of mass 500 kg can travel in the FTP(Federal Test Procedure) test drive cycle using standard ADVISOR tool settings. Step 1: We load the ADVISOR tool for the EV_defaults_in file with…

AIM: To learn about all the forces acting on the vehicle and to calculate the power needed for the vehicle to overcome all the opposing forces.   1. What should be the maximum speed of the motor used in an electric scooter capable to run at 90 kmph, if the fixed gear ratio is 7 and tire size is 90/100 R10 53J?…

AIM: To create a Rankine cycle simulator   OBJECTIVES: Calculate each state point of the Rankine cycle using the given inputs. Plot the T-s and h-s plots for the given inputs. Calculate Net work output and Back work ratio.   INTRODUCTION: The Rankine cycle or Rankine Vapor Cycle is the…

AIM: To write a function that extracts the 14 coefficients and calculates the enthalpy, entropy, and specific heats for all the species in the given data file.    OBJECTIVES: Calculate the molecular weight of each species and display it in the command window. Plot the Cp, Enthalpy and Entropy for the…

AIM: To write a code in MATLAB to optimize the stalagmite function and find the global maxima of the function.   THEORY: Genetic Algorithm A genetic algorithm (GA) is a method for solving both constrained and unconstrained optimization problems based on a natural selection process that mimics biological…

AIM: To fit a linear and cubic polynomial for the given Cp data. And to write a code to show splitwise method. THEORY: 1. MSE(Mean Squared Error): It measures the average of the squares of the errors that is the average squared between the estimated values and the actual values. We take the mean of the individual…

Initial angular displacement and angular velocity are defined as a column matrix. Separate ode function in a separate MATLAB program which takes the input…

AIM: To write a MATLAB code to simulate the forward kinematics of a 2R Robotic Arm. Stepwise explanation of the code: Firstly, the input variables like length of links 1 and 2, i.e., l1 and l2 are allocated. And the values of theta 1 and theta 2 are allocated. Using for and nested for loops, various coordinates of…

AIM: To write a MATLAB code that solves an Otto cycle and calculates its thermal efficiency. THEORY: An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle most commonly found in automobile engines. The processes…
