AKKOYUN AEROSPACE / LAUNCH SYSTEM DEVELOPMENT

Dedicated access to orbit for small missions.

Akkoyun Aerospace is developing a vertically integrated small launch system for satellites that require greater control over launch timing, target orbit, and deployment.

CURRENT DEVELOPMENT

Reusable subscale VTVL flight demonstrator

PURPOSE

Validate propulsion, control, avionics, manufacturing, and integrated vehicle capability before scaling toward orbit.

STATUS

NOT OPERATIONAL — TECHNOLOGY DEVELOPMENT PROGRAM

01 — THE MISSION

Some missions need control over the launch itself.

For many spacecraft, rideshare is the right solution. For missions where timing, destination, or deployment conditions are mission-critical, the launch itself becomes part of the mission architecture.

RIDESHARE

PAYLOAD → AVAILABLE MISSION → SHARED SCHEDULE → PREDEFINED ORBIT → DEPLOYMENT

Efficient and cost-effective when mission requirements match an available flight.

DEDICATED MISSION

PAYLOAD → MISSION-DEFINED LAUNCH → TARGET ORBIT → MISSION-SPECIFIC DEPLOYMENT

Launch timing, orbit, and deployment defined by the mission, not by an available manifest.

02 — THE LAUNCH SYSTEM

Built around the mission.

The long-term objective is a small orbital launch vehicle providing dedicated, mission-specific access to orbit for small satellites and small payloads. The vehicle is a long-term development objective, not an operational launch service. Published specifications will follow confirmed engineering milestones.

03 — HOW WE GET THERE

Build small. Validate. Scale.

Before scaling an orbital launch vehicle, Akkoyun Aerospace is developing a complete reusable subscale flight vehicle. The demonstrator brings propulsion, propellant systems, thrust-vector control, avionics, guidance, software, structures, and ground systems together in one testable vehicle. The objective is to discover integration problems and validate engineering decisions while iteration remains fast and economically manageable.

The demonstrator is not the destination. It is the development platform used to reach the destination.

04 — VERTICAL INTEGRATION

We build the capability to build the vehicle.

Akkoyun Aerospace does not only design hardware. Much of the manufacturing, tooling, and test capability required to create and validate that hardware is developed internally. This keeps the feedback loop between design, manufacture, test, and iteration short and direct.

DESIGN → MANUFACTURE → TEST → LEARN → ITERATE

DTR ENG-01

COMPACT DEEPLY THROTTLEABLE BIPROPELLANT ROCKET ENGINE

DTR ENG-01 is a compact ethanol–oxygen rocket engine developed for reusable vehicle testing, control-system development and repeated operational testing.

Its architecture focuses on high functional integration with deliberately low manufacturing complexity, while retaining a configuration representative of flight hardware.

316L / 50–130% / 107 N SL / DESIGN POINT

INTEGRATED CONSTRUCTION

The engine core is additively manufactured from 316L stainless steel, allowing the chamber and nozzle structure to be produced as a highly integrated assembly.

The material choice keeps manufacturing robust and comparatively economical while supporting rapid development iterations.

THROTTLEABLE OPERATION

DTR ENG-01 is designed for operation across a 50–130% throttle range.

The internal thermal architecture is designed to maintain effective chamber cooling throughout this operating envelope.

DEVELOPMENT PURPOSE

DTR ENG-01 is intended as a reusable development engine for integrated vehicle testing, propulsion development, control-system development and repeated operational testing. The objective is not simply to produce thrust.

The engine is designed to become part of a complete integrated flight vehicle development program.

RCS THR-01

REACTION CONTROL SYSTEM THRUSTER — ITERATION 01

RCS THR-01 is a compact propane–oxygen reaction-control thruster developed for short-duration, repeatable firing.

Rather than continuous thrust, the system is designed to generate controlled impulse events for vehicle stabilization and attitude correction.

Its compact combustion chamber and nozzle architecture are designed around rapid pulsed operation, with a maximum firing frequency of 10 Hz.
