Question: In this hypothetical scenario, you have been asked to help with a model rocketry session at a local primary school to help promote interest in STEM career fields.
Your task is to create a Simulink model that will provide acceleration, velocity, and altitude profiles for a range of possible launch configurations. Students will then be able to use your tool to predict rocket performance and measure it against actual data on the day of the launch.
Therocketibeing created for the event have a 20 mrrhliameter, 80 grams of mass (excluding motor but including parachute and wadding) and a drag coefficient of 0.75. They are configured to use a motor With a diameter of 18 mm and length of 70 mm. The motors being procured for the event are the Estes B6-4, Estes C6-3 and Estes C6-7.
Each configuration will use a flat plastic sheet as a parachute to slow descent as is typical in model rocketry. These sheets have a drag coefficient of 0.75 and an effective diameter of 20 cm when deployed.
You are only required to account for forces in the vertical direction: thrust, drag, and gravity.
For the purpose of this assessment. start with the provided Simulink file. Modify the drag block to account for drag forces that vary with velocity and with parachute deployment. You Will also need to modify the engine block to model the thrust profile of each rocket motor and the variation of mass with time as the motor is firing. It is recommended that you include a check to terminate the simulation once the rocket reaches the ground upon flight completion.
Your final model must output a full acceleration profile. velocity profile, and altitude profile. You can ignore the effect of parachute launch impulse on flight trajectory.
