Public benchmark
NASA: redesigning a welded engine part as one printed part cut 100+ welds and ~35% of cost (2017).
What it means for you
NASA got there by cutting the part count and proving the redesign in a hot-fire test. Our defense & aerospace product engineering services run the same loop on your hardware. DFMA and FEA simplify it, and testing proves it, with your approval at each gate.
The public record shows what the method can do. What it does for your equipment depends on your constraints, and the free assessment tells you.
Supplier, prime, or both: we set the model and the hand-off point.
Scope, load cases, review dates, and approval gates.
Design and analysis in FEA and vibration, checked in our QC.
Drawings, analysis, and documents for your review.
Test support, changes, and the next program.
You approve the design at every gate, so nothing that affects function surprises you. If we missed something in our QC, we fix it. If a supplier can’t make a part within three years, we fix that too.

What do your aerospace engineering services cover?
Our aerospace engineering services cover the analysis and design that flight hardware needs before it flies. That means brackets, housings, structures, mechanisms, and ground support gear. Most programs feel the limits as extra weight, vibration failures, or a design that stalls in review. Each starts in the design. Margin added by rule of thumb adds mass to every unit. A bracket that resonates can crack in test, or fail an electronics box later. NASA's structural factors of safety standard shows how much evidence flight hardware needs. Without that evidence, the design review stalls and the schedule slips, one open question at a time.
Structural FEA sizes each part to the real loads. Nonlinear analysis covers contact and plasticity where they matter. Vibration analysis checks launch, flight, and engine loads before the shake table. We design in CAD, apply DFMA so parts cost less to build, and plan the tests your qualification needs. Our team includes aerospace stress engineers from flight-critical aerospace and defense programs. You approve each gate and own the models.
Can you work to our customer's review process?
Aerospace programs live and die by their reviews. Our aerospace engineering services plan for the review from day one. A design that is right but poorly documented can still stall. The reviewer asks for load cases, margins, and assumptions, and weeks pass while the answers are found. NASA's guide to technical assessment names reviews such as PDR and CDR as the points where technical measures get a close look. Gaps found there cost the most, because every later step waits on them. Each open question adds a loop of rework. Late answers also cost trust with your customer and push back the next gate.
Before analysis starts, we agree on the load cases, the margin policy, and the report format your customer expects. We work inside your templates and your release process, so nothing needs rewriting. The package answers questions before they are asked. If a reviewer raises one after delivery, we answer it. For defense programs, we follow the export-control rules your program sets, and you own every model and drawing.
Can PPS work with our OEM or manufacturer?
Yes. Aerospace engineering services from PPS fit the partnerships that are normal in aerospace and defense programs. We work in one of three models. As your OEM partner, we act as your engineering team. Operator-led, we design the hardware and work with the builder you choose.
When design, build, and test sit with different companies, problems pass back and forth. The builder works from an old drawing, and each party defends its own scope. The Department of Defense's IPPD Handbook organizes programs around integrated product teams for this reason. In a joint program, the customer and the supplier work with us in one loop.
We engineer the design and coordinate the builder in one loop. Bring your own manufacturer, or work with our network of fabricators, machine shops, and test labs. You decide how far we take the design, up to the start of production. We never run production, so we never compete with your OEM. NDAs cover every party, and you own the IP by default, set in your contract.
What do you need from us to start?
To start a project with our aerospace engineering services, send what you have, in any format. That usually means CAD and drawings, the flight, launch, and vibration loads, and the requirements your customer has set. Add the materials and allowables you use, any test results, and your targets for weight, margin, or review date. Photos help too. Missing data is the most common reason engineering projects stall, because a model built on guessed inputs gives a guessed answer. That is why we don't start the work until every data set is in.
Once it is, the first step is a free assessment of your project scope. We confirm what the work can and can't answer, and tell you what is still missing. Then we send a roadmap proposal with scope, targets, and approval gates. Every project is scoped on its own, so the roadmap sets the schedule, not a stock promise. NDAs are available before you share any files. For gaps in material data, NIST material measurement data is a good first stop.
Who owns the design and the models?
You own the design, the drawings, and the models from your aerospace engineering services project by default, as set in the contract. When an OEM or partner manufacturer is involved, the contract spells out who owns what. Some firms keep the models, or license them back to you, so every later change sends you back to them. That locks your product to one vendor and makes design reviews harder, because your team can't open the evidence behind the decisions. You receive the native CAD, the drawings, the simulation model files, and the documented results. Your engineers can then check the work, rerun a load case, or hand the package to a supplier or customer.
We sign mutual NDAs before any of your data is shared, and your files stay in our controlled project folders while we work. If your program has export-control or customer data rules, tell us at the start and we will set up the data handling to match them. For defense programs, the State Department ITAR guidance sets the rules we follow.
What happens if a prototype fails in test?
If a prototype fails in test, we find out why and fix the design. Hard engineering carries unknowns on any project: real loads, material lots, and assembly effects never match a model perfectly. With aerospace engineering services from PPS, you approve the data at each gate. A test result is then checked against predictions you have already seen, not a black box. A failure in test is data. It shows which assumption was wrong: a load, a material property, or a boundary condition. That data improves the model and the design.
When testing is in scope, we plan the test to confirm the margins that matter most. Then we correlate the model to the results, following ASME verification and validation practice. If the miss was ours, because something slipped through our QC review, we fix it. If the test uncovers a condition nobody knew about, we scope the change with you and update the roadmap. Either way, you get a clear answer and a path to a design that holds.
How are aerospace engineering services priced?
We price aerospace engineering services to the value they deliver, not the hours we log. Hourly billing rewards extra iterations, so the cheapest quote often becomes the most expensive project once tooling, rework, and field failures show up. Our incentive is to get the design right the first time. We engage by fit, not as a ladder. Gold (from $35K): you have one project and need help with it. Platinum (from $15K/mo): you have recurring work at a steady rhythm. Diamond (from $800K/yr): you have a long development program, often multi-year.
Gold is never required, and some clients start at Platinum or Diamond. These are starting points, not quotes; your roadmap sets the price. We price to the value we deliver, not the hours we log. If the value isn't there for you, we'll say so in the assessment. Our engineering consultant pricing page explains how each collection works in more detail.
