Sea Serpent one
Sea Serpent One is a medium-lift, two stage oceanic launch system. Designed to be launched and recovered in any maritime environment, it is estimated to be reused up to 25 launches and capable of performing equatorial, doldrums, polar and simultaneous constellation launches. With its two-stage aerospike toroidal engines, the Sea Serpent One will deliver payloads into LEO, SSO, GSO and deep-space, including Lunar and Mars injection.
The fairing carries and releases the payload into orbit. It is a large metal hull which is outfitted with the payload adapter to hold the payload. The payload fairing comes in two configurations with the ability to allocate mass and volume required for the payload adapter. Each configuration is able to transport multiple or single payloads into LEO, SSO, GTO and deep space.
+ Aerospike Engines
Sea Serpent class rocket will be propelled by a full-toroidal first stage engine and a plug-toroidal second stage engine. Comprising of 12 individual thrust cells and a turbo pump system, the engines are fueled by liquid oxygen and liquid hydrogen (100% green fuel). The major advantages of using first and second stage aerospike engines are: pressure compensation, 30-60% less weight than traditional propulsion engines and multiple combustion chambers (eliminating thrust cell redundancy) and the ability to fire submerged underwater (incase ballast breach).
+ Gyroscopic Auxiliary Engines
In order to ensure the rocket is launched out of the water on target and have the ability to adjust course if necessary, eight gyroscopic auxiliary engines are ignited as the ballast system releases and first-stage aerospike ignites. As well, the auxillary engines are also used for retropropulsive thrust. This enables the rocket to slow down prior to parachute separation during the recovery phase of the launch to reduce velocity of the first stage engine. These engines are fueled by liquid methane and oxygen (100% green fuel) and have a basic bell-nozzle design.
+ Ballast System
The reusable ballast system is composed of a large metal hull comprising multiple ballast tanks. Using the same principles of submarine ballast tanks, the ballast system provides horizontal stability for towing the rocket on the open ocean and vertical stability during fueling and launch.
