Lightweight Drone Frame

A stiff yet light arm and centre plate frame

Category: Topology Optimisation & LightweightingComplexity: Intermediate

0 views

An analysis of a four-arm drone frame to see stress at the arm roots, deflection at full thrust, and natural frequency. The results help cut frame mass while keeping stiffness and avoiding resonance with the motor speed.

Frequently asked questions about Lightweight Drone Frame

What is included in the "Lightweight Drone Frame" package?

Geometry and mesh prepared from your drawings; Simulation case and data files (Fluent/CFX) with boundary settings; Technical report: assumptions, results and design recommendations; Contour, vector and animation outputs ready for presentation; A 60-minute results walkthrough and two rounds of revisions.

Can you simulate my own geometry?

Yes. Send CAD files or drawings and the operating conditions (flow rates, temperatures, materials). We prepare the geometry, mesh and boundary conditions for your case.

How long does it take?

Roughly 14 working days after we receive the geometry and conditions, depending on mesh size and how many design variants you want compared.

How is the price decided?

Each project has three packages: Scope 1 (calculations) US$266, Scope 2 (calculations + FEA simulation) US$641 and Scope 3 (full engineering report + design recommendations) US$1,063, excluding 11% VAT. Pick the one that fits; more design variants, transient runs, moving parts or validation against experiments adjust the quote after a short consultation.
