Design Of An Electric Cart For Airport Terminal

  1. 1. Design of an electric cart for Airport Terminal use Ai T il Project III by Jithesh.R Guided by Prof. K.Munshi
  2. 2. Introduction • The project aims at designing an electric cart for airport personnel to move within the premises of the airport Methodology Information Collection Formulating Product Brief Defining a problem statement Final Concept Iteration on Concepts Conceptualisation
  3. 3. Problem Statement • Transportation within the airport terminal with a silent non polluting system addressing the needs of the airport personnel or passengers
  4. 4. Information Collection • User study • Data collection of the current market D ll i fh k supplying such transportation solutions • Technical data collection
  5. 5. User Study y • Interview with the Airport Managers • Interview with Airport personnel (security, engineers, workers) • Interview with passengers • Observation of the Airport • Observation of work pattern of airport personnel
  6. 6. Observations • Airport authority states that privatisation will make the airports even bigger • Currently all maintenance and service jobs of the airport are on contract basis • The contractors use different vehicles to cater to their needs • Private airline companies introduced golf carts to cater to their customers and staff Indhira Gandhi International Airport - Delhi
  7. 7. Chhatrapati Shivaji International Airport - Mumbai Private airlines like Jet Airways and Air Sahara get vehicles modified for airport use
  8. 8. Domestic Airport - Mumbai Ground Services in India
  9. 9. • Contractors use different equipments to do their jobs • The vast space of the airport demands a transportation solution to these p workers who are currently taken around in jeeps and vans in India
  10. 10. • Security and Airport Official needs to move within the terminal to look into various factors before a flight takes off and after a flight lands • Airport Officials being in fresh condition helps a lot in efficient functioning of the airport
  11. 11. • Patients and old age people who cant walk are taken care of by Airport Authority or the Airlines they are travelling by • In India usually wheelchairs are used and in case of bed ridden patients an ambulift is used
  12. 12. • Airport officials’ transportation within the terminal is a need in airports abroad and also new airports in India which are big g Cochin International Airport Incheon Airport – S Seoul, Bilbao S Sondica Airport – Northern S Spain Lambert Airport – St. Louis Korea
  13. 13. • Some products existing in the line of airport transportation solutions by MOTREC (USA) and Club Cart (USA)
  14. 14. Analysis • There is an evident need for reducing the time of travel of the airport maintenance and service crew • The same applies to the airport authority officials pp p y • A vehicle indoors is a feasible solution for efficient functioning of these departments
  15. 15. User identification From the observed four groups of users one group is selected • Airport Personnel • Airport Security • Passengers • Airport Maintenance and Service
  16. 16. Product Brief • An electric powered cart to transport airport officials within the airport terminal • Ease of ingress and egress E fi d • Relaxed and comfortable seating while on the vehicle • Easy manoeuvring of the vehicle with very small turning radius • Facility for holding files and work sheets of the officials • Low maintenance • A work time of 8 hrs before 80% battery drain (at full working condition) • Easy charging options

  25. 25. Pre – Final Concept
  26. 26. Choosing the tyres, wheels and platform • A 16 wheel (of Bajaj Sunny) was 16” used first to try out the vehicle layout • A 9” tubeless tyre and 4” aluminium wheel rim used in go- karts were identified as a better option for the vehicle • The direct motor drive can be connected via the connector shown aside
  27. 27. 1200 mm wheel base 900 mm wheel base 800 mm wheel base 800 mm width 600 mm width 800 mm width
  28. 28. Frame of the Vehicle • The final frame (1:5 scale model) of the vehicle is shown aside • The 8 batteries are accommodated in the two rectangular guide frames
  29. 29. Styling
  30. 30. Evaluation of Styling • Three tests were conducted to arrive at a conclusion on styling of the vehicle – Comparative Evaluation – Grading on each styling – Feedback on what people like and don’t like about each don t style
  31. 31. Final Concept
  32. 32. Driving posture derivation The driving posture was calculated after evaluating different people as subjects for seating ff f
  33. 33. Thermocol model t evaluate f Th l d l to l t form and d proportion of the vehicle, corresponding CAD model was made to understand the overall form
  34. 34. The front wheels are powered by two 1 HP DC motor and steering the vehicle is executed electronically by variable speed steering mechanism.
  35. 35. Final Concept
  36. 36. 1:1 Grid Proposed vehicle p at o platform From the 1:1 grid dimensions were extracted for concept detailing, the grid helped in understanding the size of the vehicle and also to find fi d problems related t i bl l t d to ingress, egress and d seating posture
  37. 37. Iterations on Final Concept Work on the back support for the occupants Steering column and ingress – egress ease
  38. 38. Accommodating the battery casing Integration of the base and g battery case
  39. 39. The design evolution is shown above, the design errors were rectified to arrive at the final product • The first two stages ingress egress was a problem due to the protruding wheel well • Folder and file holders were not placed at appropriate positions it iti

  42. 42. Simulation of usage
  43. 43. Working of the steering column for easy ingress and egress
  44. 44. Inspirations and Study of airports • To derive form and colour schemes some airports were looked into to understand aura of the interiors
