Need a specific configuration — blade count, size, Group 3 or heavy-lift, or a custom geometry? Anvil Propulsion takes on custom domestic propeller programs. Send us your specifications — diameter, pitch, blade count, application, and volume — and we'll come back with a real read on feasibility and timeline.
The catalog is ten families. Everything else — other pitches, 5×4.3, 5.1×4.6, 12-inch and larger, other duct sizes and other mounts — is quoted as an engineered program, not catalog stock.
The standard line is ten families, quoted on request. Everything outside that box is a program: engineered from your specification, referenced to your platform, and documented the same way as the catalog parts.
A pitch, blade count, hub interface or planform the standard line doesn't carry — other 3-inch pitches, 5×4.3, 5.1×4.6, other hubs, and variants of a catalog size for a platform that needs one thing different.
Diameters above the 10-inch top of the standard line — 12-inch and up — for Group 3 UAS and heavy-lift multirotors carrying real payload.
Volume programs where the propeller is a consumable: cost, consistency between lots, and a supply that does not depend on a covered country.
Tube-launched and collapse-for-deployment airframes, shrouded and ducted platforms, and folding versions of sizes the line carries fixed.
A program starts with a specification, not a purchase order. The more of this you can send, the straighter the read on feasibility and timeline comes back. If the platform was tuned on a foreign part, its part number is often the fastest way to describe what you need.
Nothing here commits you to anything. We tell you whether it is something we can build and what it would take; you decide from there.
Check the ten families before opening a program — a size that already exists is always the shorter path.
Send the specification, the platform, the volume, and the requirement it has to meet. We'll come back with a real read on feasibility and timeline.
