TCE and Chandrayaan 3

Tata Consulting Engineers Limited is India’s largest private sector engineering and project management consultancy. We have supported the Indian Space Research Organisation for many years by designing and delivering complex facilities that make heavy launch missions possible. On 23 August 2023, Chandrayaan 3 achieved a soft landing near the south pole of the Moon. TCE’s engineered facilities enabled the integration, movement, and launch of the LVM3 vehicle used for this mission.

What TCE delivered and why it matters

Solid Propellant Production Facility

This facility produces the solid propellant that powers the LVM3 rocket boosters used for Chandrayaan 3. LVM3 uses two large strap on solid boosters known as S200. Reliable production of their propellant is essential for safe ascent and correct thrust.

  • A primary casting bay with a pit that is 10.5 metres in diameter and 18.4 metres deep
  • Motor cleaning using grit blasting for thorough removal of residue
  • Large mixing units that ensure uniform blending of oxidisers and metallic fuel in polymer binders
  • Curing ovens and self propelled units that give precise and consistent thermal treatment
  • Non destructive testing using grain radiography and tangential radiography to confirm integrity of every large propellant grain

Impact

  • Safety is built in through controlled mixing, controlled curing, and complete testing of every grain
  • Indigenous production at national scale reduces external dependence and supports continuous launch readiness
  • The plant provides repeatable quality for heavy lift missions beyond Chandrayaan 3

Vehicle Assembly Building

This building provides a controlled, safe, and accurate environment for integrating different stages and subsystems of the LVM3 launch vehicle.

  • A fully air conditioned concrete structure that is 70 metres long, 50 metres wide, and 96 metres high
  • Integrated civil, structural, mechanical, electrical, and HVAC systems designed for continuous operation
  • Six sets of swing and vertically repositionable platforms and six folding platforms for safe access at many levels
  • Seven sets of mechanised horizontally sliding doors that allow smooth and safe movement of large vehicle segments
  • Assembly towers with foldable platforms at three levels for stage work
  • A 400 slash 60 tonne EOT crane for lifting and positioning heavy rocket stages with control and precision
  • Rail tracks and anchoring points on the floor to position and secure the mobile launch pedestal

Impact

  • Work continues in all weather in a clean and climate controlled space
  • Heavy lifts and access at height are done safely and quickly with less handling risk
  • Accurate alignment during integration improves schedule reliability and reduces rework

Mobile Launch Pedestal and Bogie System

This system moves the fully assembled launch vehicle from the assembly building to the launch pad and holds it stable for the final countdown.

  • A welded steel pedestal that is 19.2 metres by 19.2 metres and weighs about 700 tonnes
  • A bogie system with four wheel units at each corner that carries the pedestal and the about 800 tonne launch vehicle over about one kilometre from the assembly building to the launch pad
  • Anchoring systems for accurate and stable positioning at the launch site

Impact

  • Safe movement of a very heavy and tall vehicle over a long route within the spaceport
  • Low vibration and controlled speed to protect integrated stages and sensitive interfaces
  • Precise final placement for launch with repeatable procedures across missions

Chandrayaan 3 proves the strength of India’s space engineering and the value of careful facility design. TCE delivered the propellant plant that assures safe and uniform propellant production, the tall and precise assembly building that enables safe integration, and the mobile pedestal and bogie system that moves and positions an about 800 tonne rocket with accuracy. These are mission enablers. They turned a complex plan into a successful launch and a historic soft landing.
