PDS REPORT

Dryden Drop Tower Rig Redesign

Overview

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

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

Background – The Dryden Drop Tower

Background – 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

Background – The Current Rig

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 ¤ Accommodate 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

Secondary Internal Customer Requirements: ¤ Consistent units of parts – metric ¤ Fastener size variance ¤ Small number of assembly parts ¤ Accommodate various sized experiments ¤ Material machinability Primary Internal Customer Requirements: ¤ High speed video – 1200 fps

(Camcorder – 60 fps) 20x

¤ Vibrational dampening – 10 kHz ¤ Experiment lighting – 3 positions ¤ Withstand deceleration of 14 g’s for multiple drops
