MICROSATELLITE LAUNCH VEHICLE

MICROSATELLITE LAUNCH VEHICLE

Offering flexible space transportation services, from dedicated launches to ridesharing, to get your microsatellite into the orbit you want, on the schedule you want.

ADVANTAGES

ON-DEMAND

When You Want to Go
Where You Want to Go

Provide on-demand transport to the desired orbit and altitude, which is difficult to achieve with shared transport of large satellites. Significantly reduce the time from contract to launch by integrating in-house design, manufacturing, test and launch, and by developing a mass production system.

FLEXIBILITY

In-house Design and Manufacturing Give Us
Flexibility to Meet Your Needs

Customize the system to meet customer needs and handle sudden changes. Our flexible response ensures high customer satisfaction.

COMPONENTS

  • 1.FAIRING

    Made of CFRP (carbon fiber reinforced plastic). Protects the payload.

  • 2.PAYLOAD SECTION

    The part which carries the satellites.

  • 3.SECOND STAGE TANK

    Tanks for liquefied methane and liquid oxygen. Made of aluminum alloy.

  • 4.SECOND STAGE ENGINE

    Engine to reach orbit. Engine to reach orbit.
    Has a high expansion ratio nozzle.

  • 5.FIRST STAGE TANK

    Supplied with tanks for liquid methane and liquid oxygen. Made of aluminum alloy. Jettisoned mid-flight with the first stage engines.

  • 6.FIRST STAGE ENGINE

    Engines to reach space, consisting of 9 engines with a thrust of 60 kN (about 6 tons) per engine. A regenerative cooling and turbopump system is used. To reduce weight, they are jettisoned mid-flight.

  • 7.ATTITUDE CONTROL SYSTEM

    The gimbal mechanism changes the direction of the engine and controls the direction of thrust. This controls the attitude of the rocket.

  • 8.AVIONICS

    Equipped with computers, sensors, and communication devices for rocket control.

  • 9.STRUCTURE

    The aluminum core material is sandwiched between CFRP (carbon fiber reinforced plastic).

TECHNOLOGY

ENGINE

Rocket engines typically account for half of the total manufacturing cost. Through innovations in manufacturing technology and design, we have created engines that are significantly less expensive than conventional rocket engines, yet are high performance and can be mass-produced.

PINTLE INJECTOR

The disadvantage of the pintle injector, which makes it difficult to achieve sufficient performance, has been drastically improved through design innovations. The number of parts is reduced to one-tenth of conventional engines, while achieving high combustion efficiency.

WIRE-WRAPPING METHOD

Innovative, patent-pending wire-wrapping manufacturing technology enables fast delivery and low cost.

TURBOPUMP SYSTEM

We have developed our own components at low cost and actively use the latest technologies such as 3D printing.

PROPELLANT

The propellant is liquid methane, which has good performance and is inexpensive. Methane is relatively easy to handle, which makes it excellent for rocket manufacturing and operation. In addition, liquid biomethane, which is liquid biogas produced from cattle manure, is used to contribute to carbon neutrality. This contributes to environmentally friendly development by eliminating the problem of foul odors caused by cow manure, as well as local production for local energy consumption.

PROPELLANT TANK

We use advanced aluminum welding technology for tank fabrication. Cost reduction is achieved by producing all propellant tanks in-house, from design to manufacture and test.

MECHATRONICS

The gimbal mechanism that controls the direction of the engine jets is a mechatronic component that requires a high level of technology and is also used in our sounding rocket "MOMO". This component, which is often made overseas, is designed in-house and manufactured in Japan with domestic suppliers.

AVIONICS

Avionics are produced in-house, both hardware and software. We actively use semiconductor technology from automotive and general industrial applications as well as the latest technologies such as 3D printing to produce lightweight, low-cost components.
