Question Paper
1. A light UAV is to be designed for carrying an instrument/equipment load of 15 kgs. Its maximum velocity is 75 kmph. A pusher type piston-prop weighing 4.5 kgs capable of delivering 14 IHP is readily available.
Work out gross weight for an endurance of 4 hrs.
Carry out weight breakdown analysis.
Prepare preliminary design of the wing.
Work out major dimensions.
Prepare a 3-view drawing.
Be reasonable to assume data required with justification.
Make use of representative sketches/diagrams to compare the design features of AN-32, Boeing 737.
Which of the above is superior to the other in its own way?
Compare the aerodynamic, structural and propulsion aspects of HAL built Avro-748 and NAL designed SARAS airplane. Make use of sketches/diagrams representing these two airplanes.
3. Explain the role of aircraft mock-up in the design and development of a new airplane. Illustrate with emphasis on structural arrangement, layout and systems deployment.
4. Explain with representative sketches/diagrams the aerodynamics, structures and propulsion of the supersonic commercial jetliner Concorde.
Which technical/engineering factors were its strong points?
What forced Concorde to retire from service?
5. What are the possible locations of Jet engines on an airplane (both civil and military) Illustrate each of these with sketches/diagrams of existing/past airplanes. Describe the merits of them.
6. Bring out your choice of the location of the wing of an airplane from the following:
High wing
Low wing
Mid wing
Design for a commercial, long range Jetliner. Argue on the basis of aerodynamics, structures, propulsion and other considerations. Make use of sketches, diagrams and plots to support your choice.
7. Design a preliminary 3-view layout for a light UAV for a Vmax of 90 kmph, Wgross of 125 kg and weight of air-borne equipment is 35 kg. A pusher type piston engine of 22 IHP weighing 8·5 kg is readily available. Keep the CD as 0.025. Select suitable airfoil section and wing geometry for unmanned airplane. Assume missing data and follow proper design procedure for this problem.
Differentiate between tricycle and tail wheel configurations.
What are the advantages of lower taper ratio? Explain with a neat sketch.
9. What is the effect of the following in the performance of an airfoil:
Thickness to chord ratio
Maximum thickness
Location of maximum thickness
Leading edge radius
Location of maximum camber
Work out gross weight for an endurance of 4 hrs.
Carry out weight breakdown analysis.
Prepare preliminary design of the wing.
