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
