Recap

[Project Review]

Team’s name: Ducks on a Plane

Project: Designing a remote controlled “Heavy Lift”

cargo airplane. Competition:

Society of Automotive Engineers Aero East Design Competition.

Date and Location: May 4-6, 2007 Fort Worth, Texas.

[Project Review]

Regular class Competition:

2 hp, O.S. .61 FX Planform Area limit: 1000 in2

Maximum take off distance: 200 ft Maximum landing distance: 400 ft Maximum total weight: 55 lb

[Project Review]

High Wing Monoplane: Least amount of drag Easiest for wing prototyping Ease of construction

Landing Gear: Tricycle

Tail: High T-tail

[Project Review]

Airfoil type:

Eppler 423:• High lift coefficient• Ease of construction

NACA 0009:• Adequately avoids the turbulent airflows

induced by the main wings.

[Last Semester’s Conclusions]

Fuselage:

Cylindrical shape:• Least drag

Wings:

Calculations made for straight rectangular

wings. Calculations were made for slotted flaps

and ailerons

•Airplane Dimensions

•Takeoff Distance

•Maximum Payload

•Takeoff velocity

•Cruising velocityEES

EES allows the group to adjust the dimensions of the airplane, and to see what effect that adjustment has on performance.

[Coming Up This Semester]

Making all calculations consistent.

Taking into account that our wing will be

swept and tapered and determining the

overall performance of the airplane.

Adding Hoerner plates and a dihedral

angle to enhance and stabilize the flight.
