VERTIGO 2 Validation Review Presentation April 6, 2005

VERTIGO History Previous VERTIGO Project Objectives: Deliver a fully-functional VTOL tilt-rotor aircraft Incorporate a complete wireless avionics system including camera and GPS Working prototype of plane

History Cont. Previous VERTIGO Accomplishments: Airframe built, but not fully functional Control system coded, but not integrated with aircraft

History Cont. VERTIGO² Initial Objectives: Finish what VERTIGO started Deliver a fully-functional VTOL aircraft Make necessary modifications to existing airframe and avionics suite

History Cont. VERTIGO² Inheritance: No parts inventory Many missing parts, not recoverable Run down airframe No clear analysis of problems No clear plan on how to tackle problems

Continue development of control system but solely for vertical flight mode (hover) Repair/modify airframe to flightworthiness Integrate controls and airframe so that improvements can be made later and full functionality eventually realized Objectives Primary Objectives

Onboard Systems Hardware: Serial Connection (tethered) PIC Servos Motors System Clock

Base Communication Joystick -> Laptop -> PIC Flight Control Software (FCS) –Event Based not Continuous Polling –2 Digit HEX Signal Instead of 3 Digits

PIC Communication 16-bit Micro-controller –Converts from analog to digital –Controls 6 servos and 2 motors –Capable of serial communication PIC Basic Pro –Infinite loop of: »Reading the serial port »Updating the servos one at a time Controls –Left to right motion control –Back to front motion control –Yaw motion control –Propeller speed

What we have accomplished thus far? Working Base Station –Joystick –Laptop Working On-board System –PIC Board –Running Software Current Status (Prateek)

Obstacles Unavailability of certain parts Circuitry too complex a deliverable Original motor-controllers from previous VERTIGO team missing Project completion time frame too short –Time spent in junior design could have been utilized for working on project

Solutions to Obstacles Use of alternative parts –Standard DC motors and controller Use of DC motor instead of 3-phase motor Due to short time frame –Guidance from some members of the previous year’s VERTIGO team for ideas and development planning –Features were reduced

Pending Items What still has to be done for the tradeshow? Communication between base station and on- board system (joystick controls with PIC) Installation of DC motors on the VERTIGO craft Aircraft Repair System Integration –DC motors connected mechanically but not electrically Overall plane integration

Tradeshow Display will consist of: Three tables –Two tables for: Displaying software on the laptop Project informational brochures 2 display boards –Computer Engineering display board –Aerospace Engineering display board –Circular table VERTIGO plane
