I need a complete ANSYS Fluent analysis of a 1 500 mm coaxial ducted fan, modelled with the Actuator Disk approach. The goal is to predict thrust, pressure recovery, torque and overall aerodynamic performance so I can compare the results against empirical data already gathered from bench tests. Scope • Build or refine a clean 3-D model of the duct, spinner and hub (blades will be represented by an actuator disk). • Generate a high-quality mesh that resolves boundary layers inside the duct and minimises numerical diffusion in the wake. • Select an appropriate turbulence model for this application and justify the choice. • Run steady-state simulations first; if convergence flags unsteady behaviour, include a transient follow-up. • Post-process to deliver detailed co...

I need a concise set of structural calculations that prove a Aluminium metal plank spanning 2 m can safely carry a uniformly-distributed live load of 200 kg/m² when both ends are simply supported. I have the design, The outcome should let me that the plank should take the mentioned load and confirm that deflection and bending stresses stay within the limits of the relevant design code. Design 3D model, Material Grade, members size etc i will provide. Please provide: • Hand or spreadsheet calculations showing the full bending, shear and deflection checks. • A short summary of the governing utilisation ratios. • Any assumptions you make about material grade, lateral restraint or serviceability limits. If you prefer running a quick FEA check in software such as ...

I’m building a special-purpose machine dedicated to material handling—specifically an Automated Storage and Retrieval System (ASRS). I have the functional concept defined and now need a mechanical designer who can take it from idea to ready-for-manufacture documentation. You’ll be responsible for the full mechanical layout: frame, racking interface, carriage or shuttle, lift mechanism, and drive selection. Expect to think through load paths, safety factors, maintenance access and, where useful, integrate off-the-shelf components to keep the build practical. SolidWorks, Inventor or a comparable 3D CAD package is fine as long as the output is neutral-format compatible (STEP/IGES). Finite-element checks on critical members are a plus, but the core need is a clean, buildabl...

Simulation of elastomeric bearing pads. Use of AASHTO Type IV girders. Procedure for modeling the complete viaduct. Definition of equivalent d...

I need a full mechanical design package for an industrial tipper that will handle around 2 tons of bulk solids such as sand and gravel. The concept is settled—I’m looking for someone to turn that concept into production-ready engineering data. Here’s what the job covers: • 3-D modeling of the complete chassis, tipping bed, and hydraulic or mechanical lifting mechanism in SolidWorks (or a comparable CAD platform I can open natively). • Strength calculations and FEA to verify the frame, hinge points, and cylinder mounts for repeated duty at a 2-ton payload plus a reasonable safety factor. • Clear fabrication drawings with weld symbols, tolerances, and a parts list ready for procurement. • A concise report that explains material choices, actuation ...

I need a COMSOL Multiphysics model of a high-frequency transformer that couples the electromagnetic and thermal physics so I can focus on thermal stress impacts. The goal is to see exactly where mechanical strain develops inside the core, windings, and insulation as temperatures rise during high-frequency operation. You’ll start from the transformer’s geometric and material data (I’ll supply those) and build a 3-D electro-thermal study that includes frequency-dependent copper and core losses, convection or forced-air boundaries, and, ideally, a transient run that tracks hot-spot evolution. Once the temperature field is solved, the model should translate that field into the corresponding thermal-induced stresses so I can compare stress levels against material limits. Bec...

I need a complete engineering package for a fully-automated, single-ram stationary compactor that serves municipal transfer stations across Libya and North Africa. The unit must accept waste straight from collection trucks, guide it through a hydraulic tipping device into a hopper, then compress it into a detachable hook-lift container. Two identical containers will work in rotation so the site can keep running while one is being hauled away. Key performance and build notes • Continuous duty cycle with twin, interchangeable containers • Conventional steel fabrication only, using processes commonly available in Tunisia and Libya (no exotic alloys or proprietary castings) • Robust automation: PLC-controlled sequencing of tipping, ramming and container exchange &...

I need a complete preliminary design for a liquid-propellant rocket engine. The exact configuration—bipropellant, monopropellant, or cryogenic—will be chosen after an initial trade study, so the first milestone is a concise comparison of those three options against the mission profile, target thrust class, reusability goals, manufacturability, and cost. Once the architecture is selected, the work will expand to: • Thermodynamic performance sizing (CEA or equivalent codes) • Combustion chamber and nozzle geometry with regenerative or dump cooling strategy defined • Turbopump or pressure-fed feed system calculations • Injector layout and mixture ratio optimisation • Hot-section FEA for thermal and structural margins • Manufacturable CAD m...

Dear Sir/Madam I'm looking for an experienced motor cum EM design engineer to independently sanity-check a set of motor designs we've developed for UAV outrunner applications (BLDC/PMSM, up to ~3 kW). I don't need a redesign — just your expert judgment on whether each design is: 1. Physically feasible — geometry, winding, magnetics, and materials are self-consistent and buildable. 2. On-target — the claimed performance (torque, Kv, efficiency, losses, temperature) is realistic and consistent with the stated geometry/operating point. 3. DFM-compatible — manufacturable with standard lamination/winding/magnet processes (slot fill, tooth/yoke widths, magnet sizing, airgap, tolerances). I'd share a results pack per design: dimensions, w...

I need a full mechanical and product-design package for an automatic roof-mounted car cover that protects a sedan from rain and harsh sun/UV. The idea is a slim roof box that sits like a cargo pod yet unfolds at the push of a button, wrapping a lightweight membrane down and around the windows before locking in place, then retracting just as neatly. Your brief begins with the concept: engineer a folding mechanism that can live inside a compact shell without adding noticeable drag or weight. From there I will rely on you to create complete 3-D CAD models, parametric so we can scale to other body sizes later, along with detailed assembly drawings ready for rapid prototyping. SolidWorks or similar professional CAD is preferred, and any finite-element or CFD insights on wind-load would be a bo...

I will share rough sketches, inspirational photos and target specifications; you will refine them into cohesive, manufacture-ready designs. Expect to handle everything from ergonomics and load calculations through to aesthetic detailing, material selection and safety compliance for the Indian market. Please be comfortable working in SolidWorks or a comparable 3D CAD platform, running basic FEA to validate stress points, and preparing drawings that local fabr...
