This is a test platform craft to prove the concept of the following: A contained ship nuclear reactor, and a hybrid ion engine. Travel times of 2 weeks to Mars are guestimated possible with this craft.
About this creation

The Hybrid Ion test platform, designation XIO-001, named Pegasus, is a craft designed to test the capacity of the solid fuel ion engine, and the ship nuclear reactor design. The main hull design is 30' diameter by 54' length. Liquid fuel tank and solid fuel magazine measures 18' diameter by 36' length.

Index of Images

02 Complete ship - cutout side * Back to top *

Ship has three levels

  • Command/Crew compartment

  • Reactor power compartment

  • Ion engine room

03 Powder magazine cutout * Back to top *

The powder magazine is where the fuel for the ion engine is stored. There are two powder storage compartments, seperatable by a shaft elevator.

The outer hull of the individual powder magazine compartments is intended to blow open should there be an errant fire in a compartment. The other compartment is shielded from the burn effects of the neighboring compartment. Comparable structure and design to the ammunition magazine of an M1 abrams tank.

Magazine compartment is maintained at high CO2/low pressure environment to reduce burn possiblities.

05 Powder magazine cutout * Back to top *

The trasport elevator serves as a compartment sealing hatch when in the middle position. This position is the default park position of the lift when not performing powder transport. When in this position, should either of the powder compartments start to burn, the outer hull of that compartment will open venting the burn away from the ship. The other compartment is shielded from the burn in the neighbor compartment.

06 Powder magazine cutout - Powder transport * Back to top *

Transporting powder using the elevator from a holding compartment to the engine room.

Respirators are needed in this part of the ship due to the low pressure/high CO2 atmosphere.

  • Main ship hull/engine room

  • Powder magazine - main ship hull left

  • Liquid fuel, bulk O2, H2O, N, C storage

  • Command and crew quarters (lower right)

  • Reactor power compartment (lower left)

Command and Crew Compartment

* Back to top *

The command and crew compartment is the primary living quarters of the crew. This compartment also contains the command and communications bridge. Also available in this compartment is the external docking airlock hatch, as well as life support systems, food, medical, instrument, and spare parts/filters storage.

The Pegasus can support a maximum crew of 10, minumum crew of 5.

Standard crew compliment:

  • Pilot

  • Co-pilot

  • Science officer

  • Science/medical officer

  • Reactor room chief

  • 2 x Reactor room operation personell

  • Engine room chief

  • 2 x Engine room operation personell

Reduced crew compliment:

  • Pilot

  • Co-pilot

  • Science/Medical officer

  • Reactor room chief

  • Engine room chief

09 Command/Crew compartment - overhead * Back to top *

  • Flight control systems

  • Navigational computer systems

  • Communications computer systems

  • Wide bandwidth sensor monitoring computer systems

  • Fire suppression module (lower right)

11 Command/Crew compartment * Back to top *

Mounting equipment to hull walls is highly discouraged. Important safety issue is the hull being penetrated by a foriegn object. Emergency hole repair kits are located throughout the ship. Standard flight suit is a low pressure suite. The low pressure suit is designed to protect a crew member down to 0psi while inside the ship for an indefinate period of time. Emergency respirators are available throughout the ship.

At 0700 (left of the bridge): Lavatory/shower

Reactor Power Compartment

* Back to top *

The Pegasus sports a standard closed system nuclear reactor power unit, and high capacity battery storage system. The closed loop reactor core can be ejected from the ship should reaction control be lost.

Only a fraction of power from the nuclear reactor is needed to run the ship in it's entirety. The planned expansion of the ship design is to use the remaining power from the reactor to power an iron atomizer that will inject molten iron gas into the exhaust ion stream. By moving very heavy atoms at very high speeds as exhaust, we will get moving really fast.

20 Rector power compartment - overhead * Back to top *

  • At 1200: Primary battery storage systems

  • At 0100 (behind steam turbine): Storage supply charging system

  • At 0200: Steam turbine electric generator

  • At 0400: Steam condensing system

  • At 0700: Reactor core/heat exchange pump

  • At 0900: Fire suppression module

  • At 1100: Transforming and distribution station

24 Rector power compartment - side 3 * Back to top *

25 Rector power compartment - side 4 * Back to top *

26 Rector power compartment - ejection of reactor core * Back to top *

Reactor core can be rapidly ejected from the ship should there be a loss of reaction control. The clean fluid transfer pipes are explosively detached from the heat exchange transfer pump, the hatch door on the hull of the ship is opened and the core unit/heat transfer pump assembly, are ejected out of the ship.

Engine Compartment

* Back to top *

This engine combines a dual, reloadable solid fuel burning system with an ion accelerator. The solid propellant bags are loaded into the breach of the burn chambers. When ignited, the expanding gasses spin the turbine electric generator. The power from the electric generator passes through two step up transformation stages 1) ionize the hot burn gasses, 2) accelerate the burn gasses out the exhaust.

Heavy transmissions and dual high speed fuel pumps are not needed in this design due to the solid fuel containing it's own oxidizer. Missing from the engine room however are two nitrogen pumps to circulate cooling through various parts of the engine such as the burn chamber exteriors and high energy ion accelerating coils.

27 Engine room - closeup * Back to top *

  • At 1200: Gas turbine electric generator

  • At 0100: Stage 1 transformer

  • At 0200: Stage 2 transformer, ion power control system

  • At 0300: Compartment heating systems

  • At 0400: Compartment fire suppression system

  • At 0600: High energy ion power shock excitation system

  • At 0900: Dual powder burn chamber

Exhaust of the engine is expelled out the aft of the ship through a thrust vectoring nozzle system with the same design as the LST-001, SST-001, SS Kennedy, and Discovery-B.
