1. Team 98.02 Rocket Sled Team: Tom BartoskiBrian BitterBrian Dearolf Robert GiffordTom Koehler Customers: Dave Scott Advisor: Dr. Len Schwartz Jack Armstrong Aberdeen Test Center Mission Statement: To design and build a rocket sled for testing a warhead’s effectiveness on light aircraft armor. Approach: By gaining an understanding of missile testing and technology, we will evaluate current techniques and apply our knowledge and creativity to design and manufacture a working prototype.

2. Why Rocket Sled Testing? A low cost method to test warhead effectiveness A more repeatable and controlled testing method A safer alternative to live fire testing

3. Problem Statement Attain speed of 800 m/s Release warhead from sled Strip sled away

4. Customers and Wants Customers Jack Armstrong Dave Scott ATC Testing Crew Wants Simulate speed Simulate flight Strip away sled Simple test setup

5. Project Constraints Sled must fit L-field rails Use Zuni rocket motors for propulsion Sled must not impact target Cannot modify warhead

6. Benchmarking Testing Facilities Aberdeen (APG) Holloman AFB Eglin AFB Key Points Sled shoe design High velocity Explosive charge for separation Rocket motor mounting

7. Quality Metrics Velocity Total test time Missile impact Sled shrapnel impact – 800 m/s minimum – One work day – 90° to target – 0% area

8. Concept Generation Pusher Sled –Two sled scheme Sidewinder –Side-mounted warhead Cannon –Explosive release Slingshot –Inertial release

9. Concept Selection

10. Analysis PATRAN analysis Railshot FORTRAN program Drag coefficients from past results Check for fit

11. Prototype Components Launch Sled Powered Sled Zuni Rocket Missile & Warhead

12. Order of Events Rockets ignite Powered sled collides with barriers Electrical contact triggers LAW motor Missile separates from sled Sled collides with second set of barriers Missile impacts target
