Aim:

Learn to draw the machine components and to give the better exposure of aircraft components drawing.

UNIT - I

Machine Drawing conventions. Need for Drawings conventions - Introduction to ISI - Conventions.

1. Conventional representation of materials, common machine elements and parts such as screws, nuts, bolts, keys, gears, webs, ribs.
2. Types of sections - Selection of sectional planes and drawing of sections. Parts not usually sectioned.
3. Methods of dimensioning, general rules for sizes and placement of dimensions for holes, centers, curved and Tapered fetures.

UNIT - II

Drawing of Machine Elements and simple parts, Section views, additional views for the following machine elements and parts with every drawing proportions.

1. Popular forms of screw threads, bolts, set screws and bolted joints.
2. Various types of Riveted joints.
3. Shaft coupling, spigot and socket joint.
4. Journal, pivot, collar and foot step bearing.
5. Welded joints and welding symbols.

UNIT - III

Following simple Aircraft assembly drawings only.

1. Different types of trusses used in wings fuselage including ribs, striengers, skin, brakets.
2. Different elements of fuselage structures, bulk head, rings(frame) long rings.
3. Different types of fuselage.
4. landing gear basic elements, structural brackets, wheel, shock absorber and Hydraulic cylinder.
5. connecting rod for aero piston engine.

Note: 40% course work should be done on Drawing Board & 60% course work should be done by Computer Aided Drafting (CAD).

Equipment Needed:

1. Hardware assembly models relevant to above are needed for demonstration
2. Drawing Boards with Mini drafting machines, 60 required for strength 

Outcome:

Students are familiarized with the drawings of the air craft components.
