Aerospace

Triton Systems, DBA

Wes Kelly

"For about three decades I've worked in trajectory analysis, flight control systems and propulsion for aerospace vehicles. In aerospace, engineers face the choice: become more specialized -- or more of a generalist. Working on preliminary design in small groups or on my own, especially with Triton Systems, the choice is made for me by the need to integrate my work with colleagues in other disciplines into an overall design concept.

In doing a trajectory analysis, an engineer can [estimate] how large a launch vehicle a space mission might need, but there is still the matter of laying out the propellant tanks, wings and control systems. When it comes to placing electronic boxes on a flight deck or wheels in a wheel well, there is no alternative but to make a concept drawing so that the use of space is evident to all. What's more, almost every issue about a vehicle's build up is subject to a trade. It is not simply a matter of building one part; it is also a matter of trading them out in the overall design (or should I say "assembly"), and studying the effect. This could be mass properties, structural or thermal loads, moment balance or cost.

Currently, with much interest in small, commercial space projects (e.g., X-prize vehicles or successors cheap access to space, "space tourism") small groups of engineers are scurrying to find inexpensive means to do Computer Aided Design. My conclusion: Alibre Design is the way to go.

Prior to working with Alibre Design, my previous drawing efforts evolved from hand sketches, "cut and paste", to two dimensional drawing products such as "Canvas"; but when it came to 3-dimensional drawings, I was stymied either by the cost of genuine CAD packages or the ineffectiveness of basic products available on commercial shelves. With Alibre Design, I discovered a product that addressed my concerns.

  1. It was within my budget to get started.
  2. I could teach myself to use the product to a large extent and
  3. When I got stuck, there were several means to communicate with help desks or user groups.
  4. Coming from a non-drafting or CAD background I was able to make immediate headway.
  5. The part, subassembly and assembly structure was a valuable tool in conducting trades or doing variations on basic designs.
  6. The potential to do direct finite element analysis on resulting designs is great and I look forward to tapping it.
  7. The Alibre team is listening to my customer feedback.

As a result of using Alibre Design, I have a means to showcase a reusable launch vehicle concept for interested parties as well as an analysis tool that rounds out the development effort. "

"I think that Alibre Design is the most user friendly software I have ever had the pleasure to use. We have gone from drawing all our parts in 2D and moved into the world of 3D with absolutely no training because of how simple Alibre Design makes it.

This is a picture of a platform assembly that I drew in Alibre Design the second day I had the software. Thank you Alibre for the Great product and the excellent customer service."
