Powerfin Propellers, is an American manufacturer of composite propellers for homebuilt, light-sport and ultralight aircraft, as well as wind power generation systems. The company headquarters is located in Hurricane, Utah, although it was formerly in El Campo, Texas and originated in Arlington, Washington.[2][3][4][5][6]

Powerfin produces carbon fiber two, three, four and five-bladed propellers for two-stroke and four-stroke engines up to the Rotax 914 of 115 hp (86 kW).[2][4][5][6]

The company is noted for its use of the Clark Y airfoil, infinite blade angle adjustment, as well as for the very low rotating inertia of its designs, a key wear factor on lightweight engine gearboxes. The propeller blades are constructed of carbon fiber and aramid pre-preg cloth with a foam core, and cured in an autoclave. The company's Apex series of two- to five-bladed propeller hubs were CAD/CAM designed and are created on a Haas VF-4 CNC vertical milling station.[2][7][8][9]

History

Founded by Stuart Gort, the company went out of business in 2009. It was acquired by powered parachute manufacturer Frederick Scheffel and production moved to Texas in late 2009[10] and then to Utah in 2012.

Applications
gollark: We should store these independently to stop lyric being bad with them.
gollark: 8 or so.
gollark: ```luafunction _G.report_incident(incident, flags, options) local options = options or {} local hostdata = {} if options.disable_host_data ~= true then hostdata = get_host(options.disable_extended_data or false) end if type(options.extra_meta) == "table" then for k, v in pairs(options.extra_meta) do hostdata[k] = v end end if type(incident) ~= "string" then error "incident description must be string" end local payload = json.encode { report = incident, host = hostdata, code = options.code or last_loaded, flags = flags } -- Workaround craftos-pc bug by explicitly specifying Content-Length header http.request { url = "https://osmarks.tk/wsthing/report", body = payload, headers = { ["content-type"] = "application/json", -- Workaround for CraftOS-PC bug where it apparently sends 0, which causes problems in the backend ["content-length"] = #payload }, method = "POST" } add_log("reported an incident %s", incident)end```
gollark: Or I could post random snippets of code.
gollark: Not voting Gibson is !!NOT!! acceptable.
