I open this thread for talk about this promise new company of small launch from Canada...

The company was founded by Bachar Elzein and Neil Woodcook. They’ve developed a prototype hybrid engine with a proprietary fuel mix that has had some preliminary testing, and will be tested again this week. They are based in Ville Saint-Laurent on the island of Montreal for now, but are planning to move to a better space. They have also leased the old mine in Thetford Mines to conduct their engine tests.

The Reaction Dynamics rocket would deliver 30kg to 150kg to a nominal 500k sun-synchronous orbit for $30k to $50k per kg. So a minimum of $900,000 to a maximum of $7.5M at current prices.

They should start to show something about her engine in this month...

Looks like they can get finance of the ESA start ups programs:

Reaction Dynamics development plan is structured in 4 phases:

Phase 1: Engine Development (Prototype) with the objective to develop and test a working hybrid rocket engine. The engine represents the company’ core technology and demonstrates its ability to successfully develop an orbital launcher. The first test are planned from September 2018 with engine completion around February 2019

Phase 2: Suborbital flight (MVP) with the objective to develop and launch a suborbital launcher. This launcher will be a scalable model of the final commercial product. The plan is to have the full suborbital launcher development going by July 2019 with a launch target of November 2019

Phase 3: The Orbital Flight of the final product. The objective is to scale up the suborbital launcher to a full commercial product with orbital launch capabilities with the development to be completed by July 2020 and launch in November 2020

Phase 4: Commercialization of Reaction Dynamics` launcher with the objective to reach 20+ launches per year.

We hope they give more information about her new launcher in this new event:

The trouble is that we know exactly how big the market is for sending up to 200kg to SSO for $7.5M on a dedicated non-rideshare launcher. Rocket Lab has been offering exactly that pitch, with little competition and a proven product that's available to launch on demand. Last year Electron saw nine launches and a business case that still hasn't fully closed.

I wish these folks good luck and very successful engineering, but even if the execute perfectly on their goals, those goals may not be enough for a sustainable business.

So on to the engineering. Has there been any hint about what propellants their hybrid engine is using? That seems to be their unique innovation.

They say on their tech page that 'recycled polymers replaces [sic] harmful fuels' so it must be some bulk-available recycled plastic, something like ABS. The Aurora page says the oxidizer 'decomposes rapidly and is therefore environmentally safe' - HTP? NOx? I doubt it's anything really exotic.
