What is Vertipedia?
Vertipedia is a comprehensive online reference for vertical lift aircraft. Our goal is to provide high-quality information on aircraft design and configuration, key physical and performance characteristics, and rotors and powerplants to industry, academia and the public.

Vertipedia provides data on a wide and growing range of aircraft, from historical and experimental examples to up-to-the-minute machines in front-line service. Each aircraft provides an overview that contains basic information such as manufacturer, operational status, and number of engines. This information is available to all.

Much more complete, in-depth views, however, are available to AHS members. This includes dimensional and layout data, specific performance data, powerplant information, and data on lift and control devices such as main and tail rotors. If you are not currently a member of AHS, we provide valuable benefits well beyond Vertipedia - why not join us today?

Get started!
Vertipedia's search page provides a number of ways to locate individual aircraft, as well as manufacturer and operator information.

Finding information in Vertipedia: More specific searches can be made based on VTOL type (i.e. autogyro, helicopter, jet lift, and so on), by lift configuration (i.e. single main rotor, coaxial rotor, tilt wing), or even by operational status.

Give it a try!

Help Vertipedia grow!
Vertipedia currently contains data on 327 aircraft and 203 powerplants. 183 organizations are also represented, including manufacturers, operators and design authorities.

One day, Vertipedia will be the standard reference for all makes and models of vertical lift aircraft ever flown. But we need your help to get there. If you'd like to contribute, check out how you can get involved! We are looking for volunteers across the AHS membership to help Vertipedia grow, especially in areas like research and data entry.

Aircraft of the Month
The Aircraft of the Month for May is the Bell XV-15 TRRA .

The XV-15 tilt rotor technology demonstrator was the culmination of efforts begun in the early 1950s to produce an aircraft that could take off, land, and hover like a helicopter, but with the speed of an airplane. The rotor pylons tilt from vertical to horizontal to eliminate the speed barriers imposed on conventional helicopters by retreating-blade stall. They allowed the XV-15 to operate at speeds of over 450 km/hr (at sea level).

Ship 2 is in the Smithsonian National Air and Space Museum (Udvar-Hazy Center).
