Heavy Lift Cargo PlaneProposal Matthew Chin, Aaron Dickerson, Brett J. Ulrich, Tzvee Wood October 5th, 2004 Group #1 – Project #3
Project Introduction • The apex of design courses, work will focus on applying course knowledge to an industrial project • Project will encompass planning, design, construction and testing of a complete engineering endeavor • Teamwork and leadership skills will be an important factor in the synthesis of a complete design • Learn / Experience design process first hand from design to construction to testing
Background • Need for heavy lift cargo planes to serve energy/mining/military sectors • Short takeoff and landing (STOL) • Fuel efficiency for long range transport • Current market limited - Ukrainian-built Antonov only real contender - Antonov An-225 capable of transporting over 250 tons – only one built • An-124 – 150 ton payload capacity
Project Impact • Change air transport options • Enhance ability to distribute natural resources • Reduce shipping costs, time, and energy consumption • Broader military transport options
Project Objectives • Compete in SAE Aero East Competition to design a heavy lift cargo plane • Apply areas of Mechanical Engineering education to a real life problem: • Dynamics • Fluid Mechanics • Modeling & Simulation • Analysis of Stresses
Competition Selection • Regular Class: • Maximum wing span • One type of engine, no modifications allowed • Open Class: • No wing span restriction • Any reciprocating internal combustion engine allowed • Maximum empty weight • Micro Class: • No wing span restriction or weight limit • Internal combustion or electrical engines allowed • Winner determined by highest lift/weight ratio
Competition Selection • Open and Micro Class require more in-depth design • Selection of engine & fuel • Gearbox ratios different from 1:1 • Gyroscopic assist allowed • Regular Class requires less design decisions • Concentrate on Airfoil & Body Design • Able to compete better with schools that focus on aerospace engineering • Stevens has previously entered Regular Class
2005 Regular Class Requirements • No lighter-than-air or rotary wing aircraft • Maximum wing span of 60 inches • Take off zone of 200 feet • Landing zone of 400 feet • Single, unmodified O.S. .61FX Engine with E-4010 Muffler • Payload bay must enclose a block measuring 5 in. x 6 in. x 8 in. • Plane that lifts the most wins
2005 Regular Class Requirements • Cannot simply refine the 2004 entry • Requirements vastly different in 2004: • 10 ft. wing span minimum • 6 in. x 5 in. x 4 in. payload bay • Some components can be re-used to reduce cost: • Engine requirement is the same from 2004 • Functioning servos can be reused
Anticipated Hurdles • No group members have any previous aerospace engineering experience • Rule changes have forced the team to conceive a totally different design from previous teams • Construction irregularities must be minimized to produce results expected from theoretical design
Overcoming the Hurdles • Consultation with project advisor and past competition participants will give insight into aerospace design process • Existing research links • Techniques for design and building • WINFOIL software will be employed in aircraft design • Enables trial and error approach to augment theoretical calculations • Design can be exported to CAD • CAD drawings can be used with CNC machinery
Preliminary Concepts • Flying wing • Fuselage is built into wing, cuts down on air resistance • Reduces material required for fuselage • May be difficult to support/brace payload bay properly • Biplane • Larger wing surface area • Increase in lift • Not enough engine power supplied
Preliminary Concepts • Monoplane • Clear and distinct parts • Easy to build • High lift when right wing is chosen • Large quantity of known data • Rather “simple” calculations • Team selected Monoplane for design
Conceptual Designs • Limited conceptual designs available at this time: • No group member has previous aeronautical engineering or RC plane design experience • Competition requirements have only been available since the end of September • WINFOIL Software will be used in developing wing and fuselage design
Heavy Lift Considerations • High lift versus Wing weight/Stability • Material • Number of Ribbing • Thickness of Wing • Lesson Learned from last year • Flaps • Max lift for area • Angle of wing • Aspect Ratio • Actual Type of Wing (ex. NACA 6409) • Type of Plane (ex. Monoplane)
Future Planes:The Technology • Entire planes tested and designed on the computer • Wings • Tail Fins • Fuselage • No tedious calculations • No human errors • Easy inputs • Pretty graphs and easily interpretable results • All plane data incorporated into program
Phase I: Design Budget • Design budget does not include construction or competition costs • Employee Cost: • Wage: $30/hr (10 hrs per week, 14.5 weeks) • Benefits estimated at 50% wages: $15/hr • Total Phase I Employee Cost: $26,100 • Additional funds required to cover overhead estimated at approximately 50% of total labor cost: $13,050 • Total estimated Phase I Budget: $39,150
Future Deliverables • Conceptual design sketches • Final calculations • Metrics used in airfoil selection • Final plane design selection • Model of final design • Phase II: Construction Budget
Conclusions • Design requirements dictate the concentration on airfoil and fuselage design • Utilization of WINFOIL will enable the design team to overcome any theoretical inadequacies among team members • Large scope of project dictates strict adherence to the proposed GANTT Chart
