Attitude Control Test Bed

• Adjustable to balance test bed

• Must not interfere with range of motion

• Support up to a 100 kg satellite

CanSat

• Deployed from rocket at 2200 ft

• Two stages of controlled descent with mid-air separation

• Record atmospheric conditions and transmit data to ground station

• Protect raw egg

CanSat Competition Texas

NASA Ames Aeronautics Academy

Bike Tour: San Francisco

Alcatraz

NASA Dryden Research Center

TRAC: Tiltrotor Analysis Crew

TRAC Research

• Problem – Increased airport congestion creates additional costs and inefficiencies

• Solution – Tiltrotor aircraft utilize unused airspace around airports without interfering with runway operations

TRAC Research

Approach

• Use NASA Design and Analysis of Rotorcraft (NDARC) software

• Explore the limits of tiltrotor sizing

• Model aircraft using 3D CAD software

Working at HSFL

Problems: • Moment of Inertia • Weight of platform • Difficult to interface

with

• 1/8” Decks • Smaller Aluminum

Extrusions • Uniform hole pattern • Two layers

Test Bed Solution

Battery Box for HSFL

Vents allow pressure to

equalize

Gaskets and lids contain

liquid in case of broken cells

Retainers support cells

and help route power cables

Design/Build Process

Tension Wheel

Clamp

Heating Element

Mechanism used to release antenna from stored position after

deployment from launch vehicle

Examples of components that I

machined for use in a satellite scheduled to

launch next year

Examples of enclosures that I

machined to contain flight

hardware on the satellite

Cold Gas Propulsion System

Custom converging-diverging nozzles

Senior Design Project: • 1-axis maneuver test apparatus My Duties: • Design custom nozzles for thrust • Machine mounting plate, parts and

test bed adapters • Compute orbital maneuvers and fuel consumption

Space Grant Fellowship Fall 2013

• More powerful microcontroller

• Feedback from IMU • Mathematical model • Maneuvers accurate

to within 1-degree
