  • WATCH POD II HIGHLIGHT VIDEO
OVERVIEW

For the second competition WARR Hyperloop developed a completely new design with the goal of achieving the highest possible speed in the tube. With a mass of only 85 kg and a maximum acceleration of 0.9g, the new pod reached 324 km/h and won the competition.

TOP SPEED

0 km/h

MAX ACCELERATION

THE SUBSYSTEMS
PROPULSION

ELECTRIC MOTOR

  • A 50 kW motor provides 40 Nm of torque, accelerating the pod from 0 to 350 km/h in twelve seconds
  • A belt drive transmits the required power and protects agains overload
  • The drive wheels polyurethan coating provides a high friction coefficient and helps absorb shocks
  • Pneumatic muscles clamp the drive wheel to the rail using a force of 1400 N
  • Due to the clamping an increased amount of torque can be transferred to the wheel, allowing for a higher acceleration
STRUCTURE

CARBON FIBER REINFORCED PLASTIC

  • Made of CFRP supplemented with aluminum inserts at points with high loads
  • Sandwich-structured main frame with a foam core for increased bending and torsional stiffness
  • Structure reinforced at critical points (e.g. brakes, propulsion connection) by varying ply thickness
  • Unidirectional fiber layout in the propulsion structure to support the belt pretension (2000 N) and prevent buckling
  • Combined weight: less than 20 kg
BRAKING SYSTEM

AND PNEUMATICS

  • Four pneumatically-activated friction brakes achieve a deceleration of up to 2.4 g, bringing the pod to a standstill within five seconds
  • In the event of power loss the brakes automatically deploy
  • Tested up to 400 km/h
  • System mass: 4 kg
POWER SUPPLY

LITHIUM POLYMER BATTERIES

  • A 132-cell lithium-polymer battery system provides all the on-board power
  • The battery packs are sealed in a CFRP box with a controlled internal pressure of 1.1 bar (16 PSI)
  • The 50 kW motor is powered by a high-voltage circuit with 500 V voltage and 180 A peak current (120 cells)
  • The electronics uses a low-voltage circuit with 24 V and 3 A (12 cells)
STABILIZATION SYSTEM

HORIZONTAL & VERTICAL

  • Stabilization modules prevent the pod from deviating in horizontal and vertical direction
  • High precision bearings ensure safe performance at high rotational speeds
  • Aluminum wheels are optimized to withstand high loads and irregularities of the rail
  • A combination of tension springs and dampers is used to counter vibration and achieve the precise alignment needed at high travel speeds
ELECTRONICS

TELEMETRY & CONTROL

  • 38 Sensors constantly assess the state of the pod, measuring everything from battery voltage to braking pressure
  • Three independent microcontrollers on custom printed circuit boards share the work of pod control
  • A common CAN Bus connecting the three microcontrollers provides a robust and industry-proven communication protocol
