  • Obstacle Avoidance worked in Loiter & Auto modes on Houston

  • Houston landing gear broke - they fell from >30m

  • Pegasus is all good

Next Flight Test

@Alison Thompson

  • Saturday Feb 3 before mech worksession

  • Pegasus efficiency testing (with cabin )

Upcoming Team Events

@Alison Thompson

  • Do we want to do a mech social soon? any ideas for what and when?

Last Work Session

@Alison Thompson

  • Got one Pegasus 2 layup done!

  • PEEK inserts are done and glued into the tubes

Next Work Session

@Alison Thompson

  • Pegasus 2 center block

  • Pegasus 2 arm connectors

  • Antenna tracker sheet metal bends

  • PEEK Standoffs for peggy 2

  • Working on getting the composites room for Saturday to do second peggy 2 plate, Rocketry has it booked but I’m trying to find out if we can share

Electronics Cases

 

 

Frame

@Alison Thompson

  • @Nathaniel Li got the changes to the center block and arm connectors done, @Billy Karantzoulis and @Evan Janakievski did a great job on the drawings! ready to manufacture

  • Meeting with @Hao Gao and @Ben Lovegrove about landing gear, we have 2 ideas we’re going to explore, a resin print similar to the current design and a design with bushings that are properly located to ensure the the landing gear stays

Cabin

 

  • @Evan Janakievski @Sohee Yoon do you have time this week to get the cabin assembled and on the drone before the flight test on Saturday?

    • @Sohee Yoon: I’ll have the new mounts printed with the heat sets by Thursday. But if we want to set up the other components I’m available Wed-Fri after 2 pm.

Houston

@Alison Thompson

  • Houston took a hard fall this weekend, we need to remake the landing gear legs, @Smile Khatri has ordered aluminum so once it is waterjet we just need to do the bends and replace the legs

  • Task coming soon to upgrade landing gear to stop from tipping over when landing with some horizontal velocity left (waiting on weight requirements)

  • New tasks for electronics mounts coming!

Antenna Tracker

@Arjun Mandair

  • Added tasks for DXFs and Drawings in Asana

Example Bent Part Drawing

@Conall Kingshott

  • Will add to drawing standards soon

  • Make this from the flat view from the flat pattern, the bend lines should come in automatically

  • Dimension distance from nearest edge to a bend line

  • Give overall dimension on the flat pattern as reference dimensions

  • Give overall dimensions of the bent parts, this is not super useful, but good practice.

 

New Tasks

 

  • Houston lidar mount V2

  • Houston rangefinder mount

  • Houston OFS mount

  • Milling task for Thrust Testing Rig

    • image-20240130-212943.png

       

  • DXFs and Drawings for antenna tracker in Asana!

  • Cabin

    • Windows - Windows - Mechanical - WARG (atlassian.net)

    • Aero simulations will come in future weeks for anyone wanting sim tasks.

      • Just need to discuss changes that will be made to the shape of the cabin and other adjustments that will factor into general shape for sims

    • Stairs?

      • Did we want to integrate in the current cabin or second iteration of the cabin (if changes are made)?

        • stairs should be in the next version of the cabin we manufacture, which is hopefully the last version - @Alison Thompson

      • Possibly the doors working as the stairs

Drafting Guideline Update

@Conall Kingshott

We are making changes to the drafting guidelines to have less cluttered drawings. If anyone has questions, concerns, or comments on guidelines generally, please voice your opinions. This applies the the changing guideline, and any other existing guidelines.

  1. Drawings to be machined should be made with millimeters as the primary dimension. For drill, end-mill & reamer sizes, stock sizes, or parts that are being made by a machinist, dual dimensions should be used with mm as the primary dimension and inches as the secondary dimension. This can be done using the smart dimension feature, by configuring it in the side menu. In very limited scenarios, a part being made by a machinist may have a drawing that uses exclusively imperial dimensions, this should only be done with mechanical lead approval.
