Helicopter upgrades increase capacity, reduce vibration

STARS’ red helicopter has long been a symbol of hope and rescue in the vast expanse of Canada’s rugged landscapes. For decades, our specialized air medical crew and pilots have flown to deliver critical care in some of the most remote and challenging locations.

Now, STARS has elevated its mission to a new level with the introduction of the Airbus H145 D3 helicopter. This conversion from the D2 marked a leap forward in technology and capability, and promised faster, safer, and more efficient missions. The cutting-edge advancements of a D3, the journey of its implementation, and its transformative impact mark a new beginning in airborne medical rescue.

The conversion to the H145 D3 introduced many major updates that enhanced the helicopter’s performance and reliability. The most significant change is the addition of a fifth blade, along with changes to the structure of the blades, an increase in weight allowance, removal of anti-vibration hardware, and a new rotor head.

The addition of the fifth blade significantly increased the useful load of the helicopter, simplified maintenance operations, and improved ride comfort for both passengers and crew. It also ensured less vibration throughout the aircraft, allowing several anti-vibration devices to be removed, and increasing weight
allowance by around 100 kg.

“When you add a fifth blade, the whole frequency of the aircraft changes,” said DJ Lafrance, STARS fleet support manager. “So, vibration absorbers and dampers are no longer required at all.”

The new assembly at the top of the helicopter involves an advanced Bearingless Motor Rotor (BMR), which is a simpler design that reduces maintenance costs. It makes the D3 rotor far less susceptible to gusts in comparison to the D2, further improving our ability to complete missions in harsh weather and climates.

“We are impressed by the increased performance and capabilities that the five-bladed version of the H145 brings to our operations,” said David Harding, STARS chief aviation officer. “It is uniquely matched to our demanding mission requirements and provides a remarkably smoother ride, resulting in
an even better clinical environment for our patients.”

While we embraced this generation of our fleet, the Airbus H145 D3 stands as a testament to STARS’ dedication to innovation and excellence in emergency medical services.

With its enhanced capabilities, increased efficiency, and unparalleled stability, the D3 is more than just an upgrade — it’s a powerful tool that enables STARS to continue saving lives with greater precision and effectiveness. In a place where every second counts, the D3 ensures that STARS remains at the forefront of airborne medical rescue, ready to respond whenever and wherever it’s needed most.
