  1. XR 71 Timothy Garner Advisor Dr. Ma ET 493 Senior design Spring 2012

  2. ABSTRACT • Design a fully functioning hovercraft with the ability to hover over land and water. • The hovercraft will be comparable to a professional model of similar size and power. • The hovercraft will have unique design aspects not found on the professional model equaling any differences performance. • The hovercraft will cost less and take less time to build .

  3. Benchmark Basic Criteria UH-13PT Twin Trainer • Max capacity 500 lbs or 2 people • Max Speed 35 mph • Hover height 8 inches • Length 13.6 ft • Width 7ft • Gross weight 350 Lbs • Flotation 1500 Lbs • Climb Gradient 20 to 30%

  4. XR-71 Basic Criteria UH-13PT Twin Trainer • Max capacity 800 lbs or 4 people • Max Speed 35 mph • Hover height 8 inches • Length 14ft • Width 7ft • Gross weight 300 Lbs • Flotation 1500 Lbs • Climb Gradient 20 to 30%

  5. Goals • To design the major systems of the hovercraft: Hull, Lift, Thrust, Controls, Extras • Design, test, and fabricate systems of the hovercraft • Gather materials needed to complete project. • Demonstrate hovercrafts abilities to perform objectives. Such as structural integrity of frame, power and functionality of the boat.

  6. Equipment • Drill • Grinder • Drill Bit • Welder • Rivets, washers • Conduit Bender • Clamps • Angle finder

  7. Schematics of Hull

  8. HULL Material Aluminum tubing Welding 2 Part Expanding Foam Fiberglass Resin Luan Wood

  9. Methods • Cutting • Aligning • Welding • Level • Forming

  10. Hull • Frame • Flooring • Nose • Coating the Hull • Outer Shell

  11. Motor Calculations Variables #include<iostream> #include<stdio.h> usingnamespace std; int main() { //declare variables double height = 0.0; double width = 0.0; double length = 0.0; double area = 0.0; double Phi = 0.00238; //inpute items cout << "Enter height this should be from .5 to 1 inches off the ground: "; cin >> height; cout >> "Enter width in inches: "; cin << width; cout << "Enter length in inches: "; cin >> length; cout << "Enter area of boat area should be in inches square: "; cin >> area; //Calculate cfm CFM = (2*height*(length + width))*squar(((2*width)/(area*Phi))) //Calculate cout << "Your CFM is is: " << area << endl; return 0; // end of main function } Power Range Durability CFM Required

  12. Lift System • Main Shaft • Vent • Skirt • Fan

  13. Thrust System • Framework • Duct • Power Train System • Fan

  14. Control System • Steering • Ignition • Throttle

  15. Enhancement Conceptual Outcome Additional Design • A lighter hull • Landing system • Larger passenger area • More Powerful • Amenities

  16. Cost Comparison UH-13PT Twin Trainer XR 71

  17. Time Line

  18. First Semester Goals • Lightweight frame • Strength of hull • Collection of materials
