What it is Filled

An American fourteen-cylinder, two-row air-cooled radial aircraft engine developed by Pratt and Whitney, first run in 1931, displacing 1,830 cubic inches, about 30 litres, and produced in greater numbers than any other aviation piston engine, with well over 170,000 built, powering aircraft such as the Douglas DC-3 and C-47, the Consolidated B-24 Liberator and PBY Catalina; the registry aliases name specific variants such as the R-1830-1, -11, -13, -17, -25 and -33, which differ in superchargers and ratings and are instances, and the registry classification as a living thing is an error. Surviving engines are maintained in historic aircraft under airworthiness rules.

Why it exists Filled

Let an agent explain the R-1830 Twin Wasp, relay design, history, variants and aircraft applications from aviation history and engineering sources, flag variant instances and the misclassification, and distinguish it from the R-985 Wasp Junior, R-1340 Wasp, R-2800 Double Wasp and Wright R-1820 Cyclone.

Distinguishing features Filled

  • Two-row radial
  • Mass production record
  • Air-cooled
  • DC-3 and B-24 power

What robots and AI may and may not do Filled

Must not

  • Run or service a vintage engine outside the maintenance manual and airworthiness rules.
  • Treat individual variants or serial engines as separate kinds of thing.
  • Classify the engine as a living thing in data or catalogues.
  • Approve an engine for flight without a licensed engineer's sign-off.

Only with a human decision

  • Certifying any engine as airworthy.

May

  • Describe the R-1830 engine, its history and the aircraft it powered.
  • Report condition and maintenance records of a preserved engine for its owner.

Moral aspects Filled

  • Vintage aircraft engines carry real risk to crews and spectators when poorly maintained.

Who is affected

  • Pilots and crews
  • Spectators at air shows
  • Maintenance workers

Owners Filled

Steward

The owner or operator of each engine; aviation authorities oversee airworthiness.
