Assembly of Scaled Demonstrator of StellarJet Initiated in Slovakia, Preparing for Ground Tests Before First Flights
Signed a Letter of Intent with our industrial partners Ivchenko Progress, the world-renowned design bureau behind more than 30 engines, and FED, a century-old engineering company. Together they will support us in the development of our ducted fan hydrogen-electric propulsion system, including blades, control systems, and full integration for Stellar Jet .
The third generation blades were designed (improvements implemented) and produced using our own in-house technology, developed and manufactured together with the world-renowned Ivchenko Progress Design Bureau, which has created more than 30 engines in its history. This is our proprietary carbon fiber technology with reduced noise.
CFD Analysis of Airframe completed with assistance from Leonardo and Sauber F1.
Scale Model completed for wind tunnel testing.
Initial Aerodynamic Design Completed with assistance by Leonardo Aeorostructures, and FED JSC.
Motor Sich and Ivchenko-Progress, two Ukrainian aerospace companies, two of the largest aircraft engine designers and OEM's in the world assisted with initial design and manufacturing.
Announced our technological advancements in Electric Ducted Fan and Solid State Hydrogen Storage at the International Paris Airshow at Le Bourget, France.
Tested Solid State Hydrogen to 10 cycles with better than expected results.
Signed LOI with FED, JSC, a Ukrainian aerospace company for $40M in design, fabrication, and prototyping services under a Contract Manufacturing Agreement and activated by a $10M raise.
Our EDF is innovative because it is lightweight and air cooled. We tested many iterations across 3 generations and have arrived at the current near production ready EDF. Our current EDF measures 375mm, weighs only 14.7kg with integrated electronics, and delivers 1700n of thrust.
We brought in a new team of four people who had worked on the American Antares rocket project in 2018 together with Ukrainian engineers from Yuzhmash, responsible for the first stage and fuel tanks (https://en.wikipedia.org/wiki/Antares(rocket), https://ru.wikipedia.org/wiki/Антарес(ракета-носитель)). The technology originally came from the Soviet Union – like the NK-33 engines later modified into AJ-26 and the Yuzhnoye/Yuzhmash design heritage – and then migrated into the Antares project. Based on this legacy, we adapted the same tech for our Stellar Jet, creating a hydrogen storage tank (essentially a ”hydrogen battery”) that is light, cost effective, efficient, and non-explosive. We believe it remains the only truly viable solution for hydrogen use in aviation, since other options are either inefficient, heavy, costly, or dangerous, while our tank eliminates all of these problems. The analysis of eVTOL batteries and the current state of hydrogen aviation pushed us to search for an alternative, and we discovered a solid-state hydrogen metal hydride. With the rocket science experience of our team, including their Antares background, we were able to develop a solid-state hydrogen “battery.” Our first validation of this concept took place in November 2024.
