Here is one of our experimental 3D printed Hadfield liquid rocket engines going through some thrust vector control (TVC) profiles! As we scale to our first light-lift orbital launch vehicle, Tundra, and then our medium-lift reusable launch vehicle, Titan, precise control of the rocket at every phase of flight is critical to mission success. Guiding a rocket to orbit, and eventually back to Earth, demands close coordination across every sub-team. Some of the key challenges we’re tackling: ➡️ Reliable & repeatable TVC actuation: ensuring the engine gimbal responds consistently across every test and flight ➡️ High-frequency control loops: real-time systems that keep the vehicle stable from liftoff to orbital insertion ➡️ Propellant sloshing: accounting for the movement of fluids in tanks and its effect on vehicle dynamics ➡️ Wind shear compensation: countering atmospheric disturbances during ascent ➡️ Structural bending & flex modes: managing how the vehicle’s primary structure responds to aerodynamic and thrust loads ➡️ Precision payload delivery: hitting the exact target orbit, every time Our team at NordSpace has been advancing our propulsion systems on many fronts, as we work to unveil our orbital-scale, pump-fed Hadfield and Garneau rocket engines in the near future — the engines that will carry Canada to orbit for the first time, and unlock sovereign access to space. Check out some of our rocket hardware, meet our engineers, join over 400 attendees and over 40 speakers at the Canadian Space Launch Conference, taking place this May 5th in Ottawa.

Hyundai Rotem has released a video introducing the LRAAM missile. It is currently being jointly developed with LIG Nex1. The integrated ducted ramjet propulsion is shown briefly. ●The difference from the initially revealed LRAAM is the addition of strakes. ●Since South Korea's numerous air-launched strike missile programs are considered first and the existence of the MBDA Meteor, the development period is generous and is scheduled to end in 2032. ●The consortium is competing with Hanwha Aerospace. ●The SRAAM short-range air-to-air missile is being developed by LIG Nex1. ●The solid fuel gas generator generates fuel-rich gas through primary combustion. Air entering through the air intake is mixed with the fuel-rich gas and then combusted a second time in the combustor to generate thrust. ●Ducted ramjet or ducted rocket propulsion systems simplify the fuel supply system and are lighter than liquid-fuel ramjet propulsion systems. Liquid-fueled ramjets offer better fuel efficiency and fuel supply control. However, they require additional fuel handling and are more expensive and heavier. ●As part of the recent success of its ground-launched hypersonic cruise vehicle, Hyundai Rotem also released CG of an air-launched hypersonic anti-ship cruise missile. The disclosed information mentions the use of hypersonic cruise missiles on land, sea, and air, and Hyundai Rotem is considered to be leading the way in cutting-edge engine and materials technology. ADD and Hanwha Aerospace are also participating in this sensitive program.
