SOLAR CELLS

• A solar cell converts solar energy to electrical
  energy
• Photons in sunlight provide the energy that moves
  electrons from one layer of a semi-conducting
  metallic wafer to another
• The movement of the electrons creates a current.
• silicon and gallium arsenide cell are used

BODY CHASSIS
14
BODY CHASSIS

• The main goals in designing the body are to
  minimize the aerodynamic drag
• Minimize weight, and maximize safety.

15
CHASSIS
TYPES -

• SPACE FRAME
• SEMI-MONOCOQUE OR CARBON BEAM
• MONOCOQUE

16
CHASSIS SYSTEM

• A space frame uses a welded or bonded tube
  structure to support the loads and the body
• The semi-monocoque or carbon beam chassis uses
  composite beams and bulkheads to support the
  loads and is integrated into a non-load bearing
  composite belly pan.
• A monocoque chassis uses the body structure to
  support the loads.

17
MECHANICAL SYSTEM
18
MECHANICAL SYSTEM

• Designed to minimize friction and weight.
• INCLUDES
• Suspension-
• Independent spring Wishbone type
• Axle
• Tyre Wheels

19
STEERING SYSTEM

• FUNCTION-
• To meet turning radius handling requirements.
• TYPES -
• Bar linkage steering

STEERING SYSTEM
