How it works
Operating cycle
How StarRoad proceeds from launch preparation through orbital operations, landing and servicing.
PreparationLaunch chamberPreparing the shuttle, accelerator, gateway and magnetic levitation.Expand stage
The loaded shuttle is placed in the launch chamber near Batanga. The shuttle’s onboard systems are tested, followed by the accelerator systems. A pre-launch test of the gas-dynamic gateway is then performed. The onboard superconductors are energised, magnetic levitation is activated and checked, and the tunnel is under vacuum. On command, pulsed power begins to be supplied to the initial accelerator segments.

- 0–330 miles. Starting longitudinal acceleration ~4g. Significant energy share on levitation and gravity overcoming.
- 330~1800 km (the lower part of the S-arc). Smooth decrease in longitudinal acceleration from the start 4g to 0The chain passes through underground arches, experiencing overloads until ~4g. Trajectory is stabilized by surrounding EM elements.
- ~1800–2050 km (upward part of the S-arc). The acceleration drops to zero as you approach the gate. ~11 km/s last 50 - I 'm not .
GatewayVacuum-to-atmosphere transitionSequential activation of the gas-dynamic barrier and mechanical gate.Expand stage
Thanks to a high launch point, the boat reaches a height of >10 km above sea level already ~30 km from the gateway, minimizing the impact of the shock wave on the territory. The gas-dynamic gate belt test is run a minute before the boat is launched without opening the mechanical gate. After a 45% of the tunnel track is passed by the vessel, a supersonic flow of compressed air is passed through the gate belt accumulated when vacuum pumps of the last section of the tunnel are created. The hydrogen is fed and activated in the combustion mode of the gas dynamic barrier system, ~10 seconds before the vessel passes. By creating a stable supersonic flow of hot partially ionized conical gas. With the subsequent opening of the mechanical gateway 3 seconds after successful belt activation and the creation of a hot barrier-grade cone.
The barrier also prevents loss of vacuum in the tunnel and softens the initial thermal shock. Within milliseconds, the shuttle passes through a prepared region of rarefied and heated gas. This key technology changes the time profile of the initial aerodynamic loading, eliminating an ultra-short shock front during the transition between media.
The gas-dynamic barrier does not reduce the total aerodynamic force. It shifts the impact load from the microsecond range into the millisecond range, critically reducing local stresses, vibration and thermal shock in the shuttle structure.
The mechanical gate closes immediately after the shuttle passes, after which the jet belts are shut down without delay.
AtmospherePassage through the dense layersA ballistic atmospheric segment with maximum loads during the first seconds.Expand stage
The belt along the ballistic trajectory, using its inertia mass and strong structure, pierces through the dense layers of the atmosphere. 10–20 - What?
It's a basic clarification. After leaving the gas dynamic barrier zone, the vessels immediately interact with the normal atmosphere at a given altitude (~3400 m). All trajectory, heat flow and overload calculations are performed based on full aerodynamic interaction with the atmosphere, without assuming the presence of a gas shield. channel or a cut-off volume accompanying it.
OrbitExit to space and orbital operationsHeat rejection, trajectory correction and payload deployment.Expand stage
After leaving the atmosphere, the radiators deploy to reject heat. The shuttle then activates its onboard electromagnetic plasma thrusters for fine trajectory correction and insertion into the target orbit—often directly beyond GEO or towards the Lagrange points. The payload is deployed. In the AstroLiner-S configuration, final insertion and orbital correction are performed by a chemical propulsion system.
ReturnDeorbitBraking and trajectory correction according to the shuttle version.Expand stage
In the full-function AstroLiner, deorbit is performed with electromagnetic plasma thrusters. In the AstroLiner-S configuration, deorbit braking, corrections and final manoeuvres are performed by the chemical propulsion system.
LandingOcean landingParachute braking, splashdown and transition to marine mode.Expand stage
Over the Atlantic Ocean near Gabon, a braking parachute system is deployed to reduce speed. The shuttle lands at a low angle of attack on a reinforced underside designed to withstand contact between the heated surface and cold water. Propellers or waterjets are deployed after splashdown.
ServicingTowing and preparation for the next flightReturn to port, inspection, thermal-protection repair and scheduled maintenance.Expand stage
The shuttle’s own motors, powered by its onboard reactor, or standby tugs in the event of a shuttle-system failure, return the vehicle to the port complex for inspection, maintenance, thermal-protection repair and preparation for the next flight. In the AstroLiner-S configuration, the return to port is provided by batteries, an auxiliary power unit or standby tugs.
Direct-exit logic
StarRoad is not designed around the need to remain in low Earth orbit. The core idea is to use the initial kinetic energy to send cargo directly towards high-energy orbits and Lagrange points, reducing the need for chains of refuelling, towing and multiple rocket launches.
In the early stages of StarRoad's development, as well as as as a basic, technologically simplified and more conservative configuration, the start version of the shuttle AstroLiner-S (Simplified / Start) is provided for .
This modification is a fully functional, yet energetically and systemically simplified version of AstroLiner, designed for initial operation of the main line, early cargo and manned launches, and to reduce the technological, operational and regulatory risks of the system.
The key idea for the AstroLiner-S
AstroLiner-S is implementing the basic StarRoad paradigm of the inertial taron atmosphere, But without using an on-board nuclear or thermonuclear power source and with full preservation of the mass-gauge launch characteristics of the basic version.
All the energy-extreme operations (disconnection, levitation, stabilization in the tunnel) are fully carried out in the ground infrastructure.
The AstroLiner-S belt is:
- by an autonomous transport apparatus,
- It's a full-fledged recycling machine.
- capable of self-orbiting, descending and returning,
- but using only chemical pull outside the tunnel,
- Not containing on board sources of high-power ionizing radiation.
Energy and superconducting systems
In the configuration of AstroLiner-S , the following are completely excluded:
- nuclear and thermonuclear power plants,
- radiation, heat and accident risks associated with them,
- The scenes of irreversible tunnel and gateway pollution.
Superconducting elements of levitation, stabilization and interaction with the trail:
- pre-charged before start,
- are transferred to a permanent mode,
- They're isolated from each other and controlled by a flight system.
The power supply of the on-board electronics, control and protection systems is provided by accumulators and inertial accumulators (machines), which are designed for a full cycle of tunnel disassembly with time reserve.
Active control of the superconducting contours in the displacement process is limited to small adjusting currents and emergency modes, which eliminates the need for a high-powered continuous power source on board.
In orbit, folding solar panels are used as an active energy source.
Motor installation outside the tunnel
All AstroLiner-S orbital operations are performed using chemical pull.
The belt is equipped with:
- medium-traction chemical marching engines (LOX/LH₂ or LOX/LCH₄ class),
- the duplicate guidance and emergency management (RCS) systems .
The motor installation ensures:
- the launching of the aircraft into target orbit after leaving the atmosphere,
- correction of the orbital parameters,
- The orbit is falling,
- controlled entrance and return.
The rejection of the electrical and magnetic plasma engines in this version is due to the absence of a high-powered power source on board and is not considered an architectural limitation of the system as a whole.
Return and Recurrence
The AstroLiner-S is capable of:
- autonomous disembarkation from orbit,
- The air is not in the atmosphere.
- aerodynamic planning,
- landing in the ocean using wings and a parachute-parafoil system.
The absence of a reactor makes it much easier:
- maritime exploitation,
- the regulation of services,
- Rehabilitation of the machine after extra-ordinary landings.
The role of AstroLiner-S in the development of StarRoad
AstroLiner-S is considered as:
- The first production version of the StarRoad,
- a platform for accumulating launch and failure statistics,
- means of early commissioning of the system,
- basic transport for the initial orbital infrastructure.
As the project progresses, compact high-power power sources emerge and experience builds, the AstroLiner-S can be evolved to complement or replace the full-featured version of AstroLiner, It's equipped with high-powered power plants and electromagnetic plasma engines.
So AstroLiner-S is not a compromise, but a logical start-up system that allows StarRoad to be operated earlier, safer and with fewer system risks, without changing the fundamental architecture of the highway.
