Tour

• There will be a tour to either Dr Shearer’s shop at 2743 Crone Rd or to the Greene County Airport on Friday 15 November 2013, from 3:30 till 5:00.

• The purpose of the tour is to see first hand how aircraft are assembled, their structure, and their operation.

6

Homework

• Homework will consist of – Definitions– Schedule Development– Tour Write up– Basic Aerodynamic Calculations– Cost Estimate– 5 minute class presentation– Draft Report– Final Report– Final Presentation

Definitions Homework

7

Schedule Development

• Students should develop a schedule time line which details interim mile stones, review cycles, draft report due dates, and final presentation/report deadlines

Tour Write Up

• Write 1 to 2 page summary of tour and some aspect of aircraft design that you felt was interesting

• You may work together on summaries, but you must complete your own work and turn in individual write-ups.

Basic Aerodynamic Calculations, #1

• Calculate the lift generated by an aircraft wing given– Airfoil– Airspeed in KIAS– Altitude– Temperature– Wing area– Angle of attack

• Can assume no loss due to 3-D effects10

Basic Aerodynamic Calculations, #2

• Students will calcuate the weight and balance of an aircraft given – Empty weight and C.G.– Removal of an existing aircraft engine– Installation of a new engine– Installation of a avionics box

11

Cost Estimate Homework

• Students will generate a cost estimate of the project once the design challenge is announced

• Example items to be included– Basic hardware costs– Direct operating costs– Transportation and other logistical costs– Personnel costs– Profit

12

Presentations Homework

• Students will identify an aircraft of interest and present data on– Gross weight– Empty weight– Range– Max speed– Stall Speed– Landing Distance– Take off distance

13

Draft Report Homework

• Teams will turn in a draft report no later than 4 weeks prior to the due date of the RWDC.

14

Final Report

• Students will turn in the final report one week prior to the due date for the RWDC.

15

Final Presentation

• Teams will develop a 30 minute presentation detailing their report. The presentations will begin 1 week after the deadline of the RWDC.

16

Homework Rules

• Home work will be NEAT and fully explained

• All homework shall be typed at the maximum extent possible

• Equations and variables will be defined

• Units for measurements will be given

• Spreadsheets will have units and labels

• You may work together on homework, but you must turn in your own work.
