Reference excerpt

Reaction Dynamics is a Canadian aerospace company headquartered in Longueuil, Quebec, specializing in hybrid rocket propulsion and small satellite launch vehicles. Founded in 2017, the company is developing a light launch vehicle called Aurora, designed to deliver small payloads into low Earth orbit using hybrid rocket engines. The first suborbital flight of Aurora was planned for 2025, followed by an orbital flight targeted for 2028.

History Reaction Dynamics was founded in 2017 in Montreal by aerospace engineer Bachar Elzein with the objective of developing a low-cost hybrid-propulsion rocket system. The company has received multiple research and development contributions from the Canadian Space Agency under its Space Technology Development Program. The largest of these was a grant of CAD 1.5 million awarded in 2020. In the same year, Reaction Dynamics completed a CAD 5 million funding round to acquire industrial equipment for its rocket manufacturing facilities. In May 2022, CEO Bachar Elzein stated that the company had secured letters of intent from approximately a dozen prospective customers across Canada, the United States, and Europe, with a combined potential contract value approaching CAD 500 million. Later in May 2022, Reaction Dynamics signed an agreement with Canadian launch provider Maritime Launch Services to conduct suborbital and orbital launches from the Canso Spaceport in Nova Scotia.

Projects

Aurora Aurora is a two-stage light launch vehicle under development, designed to place payloads of between 50 and 150 kg into a 500 km low Earth orbit. Both stages employ hybrid rocket engines combining liquid oxidizers with solid fuel. The rocket is approximately 18 m tall with a diameter of 1.8 m. The first stage is powered by eight hybrid rocket engines, each producing 34 kN of thrust at liftoff, and uses carbon composite propellant tanks. The second stage is powered by a single hybrid engine equipped with a vacuum-optimized nozzle. Aurora’s payload fairing measures 2.5 m in height and 1.3 m in diameter. A campaign of suborbital test flights was planned to validate flight hardware, launch procedures, and ground systems, and to support licensing for an orbital launch attempt.

RE 201 / RE 202 Reaction Dynamics is developing hybrid rocket engines for the Aurora launcher using solid fuel formulations that incorporate recycled polymer materials. Engine components are designed using metal additive manufacturing technologies derived from industrial 3D printing. Small-scale engine firing tests began in 2018 at a decommissioned mine in Saint-Joseph-de-Coleraine, near Thetford Mines. Larger-scale testing has been underway since 2020, focusing on two orbital-class engine variants designated RE 201 and RE 202. The most recent RE 202 test firing occurred in March 2024, achieving a burn duration of approximately 12 seconds.

RE 101 / RE 102 The RE 101 class of hybrid rocket engines was developed primarily as a test platform for Reaction Dynamics’ proprietary solid hybrid fuel. The RE 101 is smaller and simpler than the RE 201/202 and is used exclusively for static ground testing. The company reported an internal record of six firings conducted in a single day using the RE 101 platform. A secondary objective of the RE 101 program is the validation of regeneratively cooled nozzles, a technology intended to reduce nozzle erosion and improve hybrid engine efficiency. In December 2023, Reaction Dynamics successfully completed a 30‑second firing of an RE 101 engine equipped with a regeneratively cooled nozzle. The RE 102 engine, derived from the RE 101 architecture, is currently under development and is intended for use on the suborbital Aurora vehicle. The RE 102 is expected to be lighter and more compact than its predecessor.

Worked examples

Example 1 — a first encounter with Reaction Dynamics (company)

Start with the simplest possible case. Write down what Reaction Dynamics (company) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Reaction Dynamics (company) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Reaction Dynamics (company) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Reaction Dynamics (company)

In research: Reaction Dynamics (company) appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Reaction Dynamics (company) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Reaction Dynamics (company) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace companies of Canada, Private spaceflight companies, Rocket engine manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for Reaction Dynamics (company) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
