Loads Structures and Mechanisms-Top Level Organization and Ideas

  This is the link to the loads group's When2Meet which Calvin set up.

 * 1) Get direction from Systems as to who to ask for necessary information
 * 2) LSM Subgroups/Topics - Communication  [Us] 


 * 1) * Landing Gear


 * 1) *# Systems -- [Total Mass]
 * 2) *# PPT -- [Volumes] to place tanks, etc.
 * 3) * Propulsion Structure and Control


 * 1) *# PPT -- [Attitude, Mass, Thrust, Engine]
 * 2) * Lunar Architecture


 * 1) *# Mission -- [How to get to EVA] in terms of suitports, suitlocks, airlocks?
 * 2) *# Systems -- [What is the Architecture?]
 * 3) *# Crew Systems -- [Atmosphere]
 * 4) * Docking Port


 * 1) *# Mission -- [Docking Loads]
 * 2) * Capsule/General LSM


 * 1) *# Systems -- [Mass]
 * 2) *# Avionics -- [Placement] 
 * 3) *# Crew Systems -- [Atmosphere, Stowage Volume Placements]
 * 4) LSM Subgroups/Topics - Concepts


 * 1) * Landing Gear


 * 1) *# Shape Memory Alloy Honeycomb


 * 1) *## check current/power draw
 * 2) *## check costs
 * 3) *## research material properties of Shape Memory Alloy
 * 4) *## don’t use in critical EDL systems because of heating
 * 5) *##http://www.tinialloy.com/pdf/introductiontosma.pdf
 * 6) *# “Breaker” Legs with Shape Memory Alloy springs


 * 1) *## research design of “Breaker” Legs (karate boards?)
 * 2) *## research material properties of Shape Memory Alloy
 * 3) *# Conventional Honeycomb for known amount of missions


 * 1) *## how high/tall will that make the craft?
 * 2) *# Gelled Hydraulics in feet/legs


 * 1) *## does such a design exist? Is this feasible?
 * 2) *## what material for gel
 * 3) *# Airbags for unmanned cargo drops
 * 4) *# “Skycrane” Design for manned (or all) landings
 * 5) * Propulsion Structure and Control
 * 6) * Lunar Architecture
 * 7) * Docking Port
 * 8) * Capsule/General LSM


 * 1) *# Frustum Shape


 * 1) *## what is the cone half angle
 * 2) *# vibration absorber for launch
 * 3) *# launch loads


 * 1) *## 123 MPa
 * 2) *## 70 MPa
 * 3) *# landing loads
 * 1) *# landing loads


 * 1) *## 181.6 kPa
 * 2) *# Vibrational stress on launch
 * 1) *# Vibrational stress on launch

MASS AND VOLUME FOR ALL, use descent speeds from previous project for now
 * 1) *## 181 kPa
 * gelled hydraulics


 * find suitable materials
 * get temperature band
 * EM damper


 * get magnet field limits
 * power requirements
 * Airbags


 * materials
 * weight limit
 * reusability--
 * 1) drops possible
 * Basic Honeycomb
 * Basic Honeycomb


 * how much for landing
