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 321 aircraft and 202 powerplants. 182 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 April is the Boeing AH-64A Apache gunship. Originally designated the Hughes Model 77, the AH-64 was developed beginning in the 1970s by Hughes Helicopters as a replacement for the Bell AH-1 Cobra. The prototype YAH-64 first flew in 1975.

The primary mission for the Apache was as a tank killer to deter the Soviet threat to Europe at that time. The first production Apache was delivered to the U.S. Army in January 1984 and first saw combat in 1989 during Operation Just Cause in Panama. Armaments included the Hellfire anti-tank missile, Hydra 70mm unguided rocket and a 30mm chain gun mounted under the nose.

The AH-64A is still in service, but has been largely replaced by the AH-64D Longbow Apache which entered service in 1997. Its missions have expanded to also include armed reconnaissance, armed escort, and close combat support.
