Your team has been hired as a consultant to the BLOODHOUND SSC project. Mathworks has written a code which calculates the running profile as a function of different parameters. The code has been given to you and you need to produce a report detailing your recommended run profile for the vehicle to achieve two objectives:
reach a target speed of 1000 mph and maintain a speed higher than 1000 mph for a distance of more than 1 mile
complete the run in less than 10 miles.
N.B. The MATLAB m-files are available to download from blackboard under EG168?Content > Matlab and Bloodhound technical report. These m-files are a fantastic example of real-world engineering software that you might well encounter as your career unfolds.
To complete the report you will have to understand and interact with the BLOODHOUND Matlab program provided. Thus before you start you should make sure that you know the difference between a function (sub-routine) and a script/program and be aware of the correct syntax for graph plotting and simple program constructs such as if for and while loops.
**It is important that you completed all the examples in the workbook for Sessions 1 to Sessions 4 and the Lab Workbook for Session 5 (Preparation for Bloodhound project) before starting this assignment**
The items to include in your report are detailed below. The limit on the report length is 8 pages.
2. MATLAB QUESTIONS
Section 1 of the report is the Introduction (maximum 10 lines)
Section 2 of the report includes answers to the following questions (clearly label each section with the section number in your report):
2.1. Plot velocity (m/s) against time distance (m) against time and acceleration (m/s^2) against time for the given profile. (Remember to label all plots you include in the report)
2.2. Convert the quantities above in imperial units: show the code (DO NOT use screenshots) and plot velocity (mph) against time distance (miles) against time and acceleration (fps2) against time.
2.3. Create a new velocity plot with a target line at 1000 mph. Create a new distance plot indicating the maximum distance reached (you can put a vertical line or add a marker). Comment if with the given parameters the run meets the target indicated above

2.4. State your recommended Rocket start time Chute1 and Chute2 opening times to reach the 1000 mph speed to maintain the target speed for at least one mile and to complete the run in under 10 miles at 15C.
Hint: To quickly find the answer it is important to fix one parameter at the time. First modify the rocket start time to reach the target speed (1000 mph) and then change the open chute times to reduce the total distance. Different combinations are possible you need to select the one that you consider being the best for the report and comment why you chose a given combination of parameters.
2.5. For the profile obtained in Section 2.4 plot velocity against time distance against time and acceleration against time for the new profile in imperial units
2.6. Plots of velocity against distance and acceleration against distance in imperial units
2.7. Compute the average speed for the baseline profile (the original code) and for the profile identified in Section 2.4. State your answer and show the Matlab code
2.8. Plot 3D graph for Drag_Surf_kN + Velocity vs. Time_s by modifying plotResults.m
2.9. For the run profile recommended in Section 2.4 study the effect of temperatures: run the code for five different temperatures: 5C 15C 25C 35C and 45C. For each temperature plot velocity against time. Write your comments and observations.
Note: For this question you can simply replace the value of Temp_C in masterCode.m re-run the code and then capture the plot each time. You can also write a for loop as shown in the workbook for Laboratory Session 5.
3. HEALTH AND ENVIRONMENTAL SECTION
Section 3 of the report will include the answer to these questions:
3.1 Driver safety considerations (maximum 10 lines)
3.2 Environmental impact of the Bloodhound SSC (maximum 10 lines)
1. A single Microsoft word or pdf report is to be submitted per group.
2. Use a coversheet with:
a. a team name
b. your names and student numbers.
3. Save your report with your Discipline & Team Name e.g. AmazingTeam_Materials.doc
4. ONE group member to submit the report via Turnitin on Blackboard (link
available in the folder Assessments) before 4pm 12th December.
N.B. Only assignments correctly submitted before the deadline will be marked!
