>>513682524 (OP)Descent stage:
Combustion chamber with injector assembly and propellant control valves
Pressure fed propulsion system (helium).
Hypergolic propellants: fuel (aerozine -50) and oxidizer (N tetroxide)
Two fuel and two oxidizer tanks in the base of the LEM
46.7 kN thrust with throttles in 10:1 range
Ascent stage: two redundant systems operating simultaneously but either system capable of providing full control. Eight jets per system, total of 16.
Pressure fed propulsion system (helium)
Hypergolic propellants as above
1 fuel and 1 oxidizer tank.
Helium flow: two tanks at ambient pressure, explosive valves opening prior to initial engine start.
Flow through helium filters, to solenoid valves, then pressure regulators.
Check and relief valves, burst disk.
15.5 kN thrust (only powering the people capsule with some space rocks)
No throttles or gimbals
Primary Navigation and Guidance System generates commands like Engine On/Off and throttle commands.
Abort Guidance System if needed.
Option for backup manual control with throttling through thrust/translation controller assemblies
Pretty straightforward and easy to learn about if youโre not a well-poisoning female who never built a rocket/rocket engines/rocket guidance system in the back yard.
