Dryden Drop Tower Rig Redesign PDS REPORT PRESENTERS Briand Oaks & Amanda Thoreson GROUP MEMBERS FACULTY ADVISOR Tyler Milhem Dr. Weislogel Mattea Brown Pamela Wallace Briand Oaks Amanda Thoreson

Overview ¤ Background ¤ Issues and Solutions ¤ Product Design specifications ¤ Project Plan ¤ Questions

Background – The Dryden Drop Tower ¤ Experiments in free-fall experience reduced gravity conditions! ¤ 6 stories high ¤ Up to 61 drops in one day! ¤ 2.1 seconds of microgravity

Background – Background – The Current Rig The Current Rig ¤ Holds Various Types of experiments ¤ Houses video camera ¤ Provides lighting for experiments ¤ Houses batteries to power lights ¤ Contains adjustable weights for balancing ¤ Experiences ~14g deceleration

The Issues ¤ Primary Customer Issues ¤ Employs a camcorder featuring only 60fps ¤ Cannot accommodate the Phantom V4.3 ¤ Release vibrations increase g- force on experiment ¤ Current lights are not bright enough for Phantom

The Issues ¤ Secondary Customer Issues ¤ Heavy ¤ Difficult to access experiment components in rig ¤ Batteries and weights are taped in place ¤ Batteries must be removed from rig to recharge

The Solution – Design A New Rig ¤ Have an ergonomic user friendly geometry ¤ Acc ommodate all desired internal components ¤ Solidworks model and prototyping ¤ Design new rig geometry to reduce vibrational noise and rapid deceleration ¤ Finite Element Analysis and accelerometer testing ¤ Add automation

Product Design Specifications Primary Internal Customer Requirements: Secondary Internal Customer Requirements: ¤ High speed video – 1200 fps ¤ Consistent units of parts – metric (Camcorder – 60 fps) 20x ¤ Fastener size variance ¤ Vibrational dampening – 10 kHz ¤ Small number of assembly parts ¤ Experiment lighting – 3 positions ¤ Accommodate various sized experiments ¤ Withstand deceleration of 14 g’s for ¤ Material machinability multiple drops
