Determine the optimal delay for your Level 1 flight. Assignment 2 Solution: [PDF](Assignments/Assignment2Solution.pdf), [MATLAB](Assignments/Assignment2MATLAB.zip), [OpenRocket](Assignments/WeaselFromPartsE178.ork) # Assignment 3 – Due 20240201 [**Flight Modeling 2**](Assignments/assign3.md.html) – Develop a 1-D model of a rocket's flight that will let you determine the average $C_D$, the $C_D$ as a function of velocity or Mach number, and the thrust curve for your rocket. * Assignment 3 Solution: [PDF](Assignments/Assignment3Solution.pdf), [MATLAB](Assignments/Assignment3MATLAB.zip), [OpenRocket use Flight Data files](FlightData.md.html) * Assignment 3 Extra Credit 1.1 Solution: [PDF](Assignments/A3EC_1_1_Solution.pdf), [MATLAB](Assignments/A3EC1_1_MATLAB.zip), [Spreadsheet](Assignments/Assignment3ExtraCredit1Values.xlsx), [OpenRocket](FlightData.md.html#flightdatafiles/madcowminidx3firstflight) * Assignment 3 Extra Credit 1.2 Solution: Coming Soon. * Assignment 3 Extra Credit 1.3 Solution: [PDF](Assignments/A3EC_1_3_Solution.pdf), [LabVIEW](Assignments/A3EC1_3_LabVIEW.zip), [Spreadsheet](Assignments/A3EC_1_3_E12Data.xlsx), [OpenRocket](FlightData.md.html#flightdatafiles/estestopshot) # Assignment 4 – Due 20240208 [**Barometric Altitude**](Assignments/assign4.md.html) – Determine the magnitudes of errors associated with barometric altitude measurements and compare with actual flight data. * Assignment 4 Solution: [PDF](Assignments/E178_S2024_Assignment_4_soln.pdf), [Spreadsheet](Assignments/Assignment4Soln.xlsx) # Assignment 5 – Due 20240215 !!! NOTE For 2024, Assignment 5 has been made optional. The solution will still be posted after the due date. [**Analysis of Weasel Flight Data**](Assignments/assign5.md.html) – If you were able to fly your LOC Weasel with the Featherweight GPS and the Small Teensy Data Logger, analyze the flight data. If you were unable to fly your Weasel, use the LOC Weasel flight data on 11 February 2023 in the [Flight Data](FlightData.md.html#flightdatafiles/locweasel). Compare the corrected barometric altitude with the GPS altitude and the predicted Open Rocket or Rocksim altitude. Compare the measured/calculated acceleration and velocity with the predicted Open Rocket or Rocksim acceleration and velocity. Compare the measured/calculated $C_D$ vs. $v$ with that from Open Rocket or Rocksim. Compare the measured/calculated thrust curve with that from [Thrustcurve.org](https://www.thrustcurve.org). Comment on your flight data as compared to the models and data from other sources. What have you learned? What questions would you want to answer with further flights? * Assignment 5 Solution: [PDF](Assignments/Assign_5_Soln.pdf), [MATLAB](Assignments/ScanTeensyDataLoggerGPSRotTempWeaselG80.m) # Assignment 6 – Due 20240222 [**Open Rocket for Level 2**](Assignments/assign6.md.html) – Create an Open Rocket model of your Vulcanite and compare it with your analytical model and flight data. Determine the optimal delay for your Level 2 flight. # Assignment 7 – Due 20240307 [**Pass the Level 2 Exam Questions**](Assignments/assign7.md.html) – Study for and pass the NAR and the TRA exam question pool. # Assignment 8 – Due 20240411 [**Analysis of First Set of Data Collection Flights**](Assignments/assign8.md.html) – Analyze the data from the first set of data collection flights. # Assignment 9 – Due 20240418 [**Analysis of Second Set of Data Collection Flights**](Assignments/assign9.md.html) – Analyze the data from the second set of data collection flights.
