Welcome to Vertipedia!

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:

Search by aircraft name. This can be further filtered by type and variant designation, if any.
Search by country and name of primary manufacturer, as well as operators.
Search by powerplant installed.

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 867 aircraft and 465 powerplants. 395 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.

On April 20 in the history of vertical flight:

1942 - Demonstration of the Vought-Sikorsky XR-4 to the US military and Government

Featured Aircraft

Our latest featured aircraft for April is the Erickson S-64F/CH-54B Aircrane .

Entering service as the Sikorsky CH-54 Tarhe heavy-lift helicopter, this aircraft became known as the S-64 Aircrane when Erickson Air-Crane purchased the type certificates, as well as manufacturing and support rights, from Sikorsky in 1992. The S-64F models are upgraded, certified CH-54B aircraft, with remanufactured airframes.

Used in construction, logging, and firefighting around the world, these aircraft set several flight records, many of which are still current. For example, in 1971 a S-64F/CH-54B set a record for highest altitude in level flight (11,010 m, or 36,122 ft) that still stands today.

The Aircranes are unique in that they feature an aft-facing position for load master or engineer. The aircraft can be piloted from this position. While three crew are employed when carrying external loads, only two crew (as per EASA TCDS No. EASA.IM.R.003 page 6) are required to fly the aircraft.
