Drawing Assignment - Vent Sleeve

Instructions - Create a 3D model representation using the drawing representation, as shown in attached file, in PTC Creo or Solid works. Dimensions are listed in MILLIMETERS. All sketches must be fully defined, free of over-constraints, and dimensionally accurate. When complete, submit the model in CANVAS using the appropriate file naming procedure as described in the syllabus.

PROMPT -

You are part of a team of engineers that have been contracted to design and manufacture a small scale, trigger release object launcher. This launch device must fully adhere to the design parameters that have been specified by the instructor (summarized below). Your team's catapult/launcher will be evaluated by its performance in only one proctored event. This trial is to not only determine how well your group's launcher follows the initial design process, but how accurately it can fire at your competitors. The last remaining group with the most accurate target hits, will be deemed "winner" of the event. Note that this project is competitive and will require teams to work together to create a robust catapult launcher. This project is worth 500 points and will be categorized under Projects listed in your syllabus.

DESIGN PARAMETERS - The final project vehicle must fully adhere to the parameters listed below:

Launch device must fit within a 24" x 24" x 36" box. (ID points will be deducted for every 0.125" considered out of bounds)

• The entire device must stay within the 24" x 24" footprint before, during and after the launch.

Launch devices are prohibited from using any compressed/pressurized fluids, flammable, chemical or any other reactions that could pose a safety risk.

• i.e potato cannon launcher etc
• Note: the instructor reserves the right to void any project that poses an unnecessary risk to the group or any other person or structures.
• Bonus Points will be awarded for teams that use L.E.D to light up the vehicle. 2X of any accumulated bonus points will be awarded to teams that use L.E.Ds to demonstrate a programmed set of instructions.

Launch devices are allowed to use only mechanical or electrical methods to launch, throw, or otherwise project the instructor approved "objects".

• Under no circumstances will any other object be allowed to be launched during the competition.

Designs must incorporate a tested capability to aim, fire, and hit at different opponents.

 No pre-purchased "kits" are allowed - although using small purchased components are acceptable. Purchased components are generally recommended as to prevent any unnecessary "re-inventing of the wheel".

• Electric assemblies are conditionally approved and will require the instructors consent, approval and signature prior to any construction or test of the device.

Launch devices must not inherently damage the provided instructor launch objects.

Launch devices must avoid direct trajectories to the opponent shooters.

• Design must not allow the use of "Direct Fire". All projectiles must be "Lobbed" from your group's launch mechanism. See Instructor for more direct fire definitions.
• Designs should incorporate thought into a sound structural device as to prevent any damage sustained throughout the competition. Designs should incorporate protections against hardware damage from incoming opponent projectiles.

All launch mechanisms must have a "trigger" mechanism that is directly linked to the device launch component.

All designs must have a tested capability to aim, fire, and hit specified targets with 20' - 35'.

Group Launch mechanisms must undergo a thorough design process and basic manufacturing process that follows an understanding of the product life cycle.

TECHNICAL REPORT & PRESENTATION -

The technical report must have a title page, table of contents, labeled chapters/sections (that include the introduction and the topics listed below), and an appendix. Teams are expected to have the technical report free of spelling and grammatical errors, and must use figures appropriately. The report must be a minimum of 5 pages (not including the title page, table of contents, and Appendix) and must address the following criteria:

The Design Process:

Design Synthesis

• What was the intent of your design?

Design Representation

• Discuss the different preliminary ideas and illustrate each preliminary design.
• Discuss final design concept and discuss how they fulfill each criteria.
• Discuss the assembly procedure and reference technical drawings in the Appendix.

Design Analysis

• Briefly illustrate any "analysis" your team conducted to prove your preliminary concepts.

Design Evaluation

• What was your team's decision matrix?
• Was there a PDR conducted? Was there a CDR conducted?
• Out of all the preliminary design concepts listed in Design Representation, discuss how and why your team decided to go forward with your final design?

The Manufacturing Process:

Manufacturing Planning

• What were some steps involved to prepare construction of your vehicle?

Manufacturing Execution

• Describe all the steps that were used to construct your project.
• Effectively use and label figures were appropriate.
• Elaborate on any challenges that were faced throughout the project.

The Appendix:

Appendix A: Project Management

• Clearly show documentation of your group's structure
• Include a time table (Gantt Chart or any other project management timeline)
• Discuss the grading criteria or legend used when creating a Design Matrix.

Appendix B: Technical Drawings and Supplementary Documentation.

COMPETITION -

Logistics

All groups will have the ability to calibrate their shooters before the start of the competition.

Each group shooter will have a total of 5 attempts to inflict the maximum amount of "damage" to the opponent/hostile shooter.

Each shooter will start with 100 points toward their "health" for each match.

Health can be deducted by landing the approved projectile in an opponent's zone. See Figure A for heath deduction values.

Direct hits to an opponent's shooter is strictly prohibited.

Projectiles that land, graze, or strike an opponent's shooter will inflict -25 from the opponent shooter's "health".

Projectiles that land short of the Target Zone otherwise known as "No Man's Land" (See Figure A) do not affect any point values.

Projectiles that land 5 feet past the target zone will gain +10 health to your group's shooter (See Figure A).

Projectiles that land in the opponents Target Zone will inflict -5 health to your opponent's shooter.

The instructor will announce when a key spot must be fired upon.

• Landed hits within 2 feet of the announced spot will inflict "-30" health from the opponent.
• Key spots are not optional, and must be fired upon when instructed. Failure to comply will impose a "cease fire" to the next projectile launch from your shooter or -10 heath.
• Key spots can potentially be required in all "shots"

If both groups fail to strike any area in the target zone, both teams will suffer a -15 point deduction to their shooter's "health".

Shields have been discontinued for the Spring 2018 semester and will not be allowed during the competition.

In the event where a group's shooter has sustained damage and needs repair: the match will be placed on hold for a length of 1 match to allow for any group repair.

• Repairs that cannot bring a shooter back to operational effectiveness by the end of the next match, will forfeit their match.
