3 Agenda Project Description Review Customer Needs Review
Customer Requirements Review Functional Decomposition Concept Development Concept Comparison Data Collection Architecture Risk Assessment Project Planning Work Breakdown Structure

4 Project Description Glider Tether Base Station Goal: Design, build, and test a tethered, small-scale, human-controlled glider. Critical Project Objectives: Maintain maximum tension on the tether Sustaining horizontal and vertical flight paths Measure and record tether tension and position Understand the influential parameters for sustained, tethered, unpowered flight Operator w/ controller

5 Customer Requirements

6 Engineering Requirements
Yellow: Major design Biege: DAQ Grey: Test flight White: System environment

7 Functional Decomposition

8 Functional Decomposition

9 Functional Decomposition

10 Functional Decomposition

11 Concept Development Gliders Buy an RC glider
Design and build an RC glider Measurement Devices on Base Station Buy a 3-axis Load Cell Build Load Cell from three 1-axis Load Cells GPS with Force Gauge Resistance Gyro with Force Gauge IMU with 1-axis Load Cell

12 Art’s Plane Sustained multiple damages Gained crash experience
Possible tethered flight concept tests Salvage parts Sorry Art 

13 Glider Concepts

14 Buy Glider Pros: Pre-Engineered to Fly Can purchase spare parts
Fast shipping Modifiable Cons: Not guaranteed to fly with tether Expensive Limited modifications

16 Build Glider Pros: Can optimize plane for tethered flight
Build spare sparts Resources available Cons: Not guaranteed to fly Requires time to build Complex Hard to balance Could become expensive if mistakes are made

17 Benchmarking (Build) Experimental Airlines tutorials (Photon Model as baseline) Custom/interchangable design (wing, fuselage, rudder, etc.) ~$80 - $100 (~50%-70% “1 time cost”)

18 Measurement Concepts

19 Force Gauge and Resistance Gyro
Pros: Innovative Cons: Expensive Complex Data Internal Turbulence Requires current line on tether Difficult to calibrate Difficult to set up

20 3 Single-Axis Load Cells
Pros: Can repair individual components Accurate Cheap Components Cons: Difficult to calibrate Potential for noisy data

21 3-Axis Load Cell Pros: Accurate Precalibrated Intuitive Setup Cons:

22 IMU Board and 1-Axis Load Cell
Pros: Provides accurate position and orientation data Cons: Requires noise filtering Difficult to calibrate IMU system would be on glider

23 Force Gauge and GPS Pros: Digital Data Accurate force measure Cons:
Expensive GPS on glider changes weight Difficult to calibrate Difficult to set up Innacurate position

24 2 Potentiometers and 1-Axis Load Cell
Pros Inexpensive Accurate angles Cons Easily breakable Require precise machining
