Rarinn's Ideas

  Proposed engine concept is outdated. To can view newer version here . Initial concept for a vehicle that is supposed to use negative emission ammonia engine (detailed description will be published at a later date, mention of it can be found at the bottom of this post ). “Rider” sits just like driver of a car, while "pillion" is tucked bellow and slightly rearwards of the “rider”. Drive of rear wheel is parallel clutchless hybrid system ( lithium-ion capacitors act as energy storage), while front wheel has a electric motor/generator attached to it that acts as series hybrid system  (motor/generator is there mostly to achieve regenerative braking, but some power can be send to it, making this vehicle a 2WD motorcycle ). Main power producing part of the engine, along with an electric motor/generator (connected to the ICE “directly” via single-speed internally geared transmission) and gearbox (car-type 6-speed automated  “manual” with simplest possible cone synchromesh ...

This is initial proposal for a crewed lunar program. It is to be based on a large, partially reusable rocket, that is relatively simple to manufacture, placing lightweight two-person spacecraft (lander) in low lunar orbit (LLO). Spacecraft consists of one engine and only single pressurized crew compartment (but cosmonauts have individual pods with life-support that would keep them alive even after depressurization event ). Propellant tanks needed to leave LLO, along with heat shield are stored in orbit while spacecraft lands on the lunar surface. Tanks needed for initial phase of descent are discarded before touchdown.   Launch vehicle
