111518 CFD Talk with Kevin

Gage pressure vs absolute pressureo Relative pressure is zero so gage pressureo Reference pressure is zero psi

AIM needs less input boundaries Alec

o Transient model changes with longer duration Kevin’s

o ANSYS Aimo Pressure relative to sea levelo Probably 5 degree attack angle o Steady State Model o Green sections are fully body

Open Actionso Find distance between original geometry o Run Steady state model o Measure the distance between the centerline and the default axiso Model a half body instead of a quarter body to account for angle of attack o Add a 5 degree attack angle to account for gusts of wind near altitude

Look into how big those gusts are (the balloon people)

111518 Agenda Decide 2nd semester meeting times

091818 In Class Agenda:

Class will consist of: Brief Announcements Work through functional decomposition with team and Art - Claire

Initial functional decomposition diagram finished (picture will be put into Whiteboard Photos folder on the MSD Google Drive)

Art reviewed the initial functional diagram - Reword some of the blocks

Initial functional decomposition diagram drafted up into Google Drawings Review initial functional decomposition diagram on Thursday - 9/20

Review Peer Evals with Art Art didn’t need to go over the peer review Put peer review on public directory on project EDGE (Claire will do this by 9/20)

Other things to do:

Review Edge requirements for next phase and assign tasks including:

Functional Decomposition - Claire Initial functional decomposition diagram started in class Art reviewed initial diagram Review initial functional decomposition diagram on Thursday

Benchmarking Concept Development Feasibility: Prototyping, Analysis, Simulation Morphological Chart and Concept Selection Concept Selection System Architecture Designs and Flowcharts Updated Risk Assessment

Review Project requirements for next phase

Accelerometer Locations for Northeastern- Alec All MECE's learn ANSYS Cross Section Model- Claire/Tony Model simplification for analysis Nosecone Tip CAD Verification- Tony Estimate Loads on Structure- Alec/Alex/Meagan Continuous EDGE Updates- Drew Nosecone Stiffness Test Plan- Alex Tank Mount CAD-Meagan

Actions and To-dos -look into what is needed for Analysis

- List of analyses - Possible simplification of cad models - Model inputs needed

- Accel Locations - Still need Vertical test stand

- Stiffness of nosecone - Look at specs - define if average is sufficient

- Nosecone Tip Cad Verification - Tank Mount

- Touch base with Meagan on where this is at

List of model inputs - Simplified Load Path Geometry -- Solid Body Geometry - Fin Geometry - Material Properties - Fluid Properties - Temperatures- FBD- Acceleration/Thrust/Velocity

091618 Tech Talk with Kevin 2D analysis

o Reduce element count Change from 3D to 2D or 1D

List of analysis needed o Cross section view of rocket?

Stress distribution within rocket Way to do that within ANSYS or other post processing software ANSYS

o Solver and Mesher Tecplot

o https://www.tecplot.com/o Imports data from ANSYS results

Symmetry In final product, not every component will be placed exactly center Using this would be the last option, if all other options don’t pan

out Machining Bulkhead

o Does it require a 5-axis CNC? No Tank holding or engine bulkhead?

Tank bulkheado All made but need mounting setupo Need fiberglass washer

Bulkheads may reach 150 F - may need insulation Need to revisit GTech report

Engine bulkheado Need redesigned and remachined

Same footprint Radial holes need to bolt into bulkhead

Might need more material o This is FAR OUT Jrs responsibility

Prior concerns?o Manufacturing

Finishing tank mounting solution Revising the engine bulkhead

Uncertain design will survive launch

Missing fins Stability analysis near end of rocket build

o Stability is the difference between the center of gravity and the aerodynamic forces/pressures

Fin shapes decide where center of pressure goeso Easiest to changeo Small/short fins can reduce flutter

Rest of rocket hardware determines center of gravity Parachute Harness Engine bulkhead connecting to (other?) bulkhead rods

o 4 rods that need to be trimmed down at end Match Drilling - Drilling consistent bolt holes for bulkhead mounting

Will be a problem in Spring Drill holes while parts are assembled

o Recovery Ordered parachutes, ejection mechanisms, and Tender Descender The design requires both parachutes to be released from the same bay

Speed cannot be reduced too much during descent because cross breeze can cause the rocket to drift away

Drogue parachute drags out main parachute Pull tests

Tender Descender sheath needs to be purchased Link for sheath dropped in Airframe folder on Google Drive

091318 Agenda Run through edge

o Still need Team Values and Norms - Alex Planning and Schedule - Tony Meeting Notes - Meagan (Meagan got the notes into Word and Claire

linked it to EDGE) Design Review - TBD Planning Next Phase

Prep for Review on on Saturdayo Run through gantt chart and incorporate feedbacko Show up early at 10am Saturdayo Show Art how to use skype for business to connect into meeting (Meagan @

noon) Plans for Next Phase

o Subsystems Peer Review

o Can still talk about it on Saturday Self reflection first

Pros and Improvement Review GT Structures Report

o What do we want Kevin to go over? 2D analysis List of analysis needed

Take turns leading class meetings

o Who volunteers for Tuesday Drew -> Tony -> Alex -> Alec -> Claire -> Meagan

o Preps agenda and sends it out early and asks for inputo Talk about how it goes and incorporate feedback (learning experience :) )

9. Review Customer Requirements Questions10. Key times

a. Problem definition Review Saturday 15th at 11am

090118 Vertical Test Stand Design Review Specs

o ~11 ft tall Tank Fit Up info

o ¼” holes for the mounting o Recessed on one side

Mounting plateso Look into removing bottom plate below engine

Or if keeping plate need a large clearance Data Collection

o Accelerometer needs to be purchased by northeastern Would like multiple accelerometers

Min 2 because it’s a noisy sensor Could try for vibrations at joints

o Load cell One purchased and one to buy by northeastern Issues with positioning because needs to be thru holes relatively close

Stand designo Are we sealing off electronics?

COTS box and clear coat (ie nail polish) Testing

o Failure analysis for leak testing Fails under what load

o Sealing with kcl Kcl vs npt

o Order min 3 tanks (have one ported with potentially npt) Almost if not identical to the seamless Keep one as backup

o Proof to leak check Do not change configuration

Further Design o bulkhead / tank adapter design

Change part of the loadpath o Use a teflon O-ring seal (ie cryo seals)

Proof of concept by chilling and crushing/pressing
