“FLOW AROUND CONCORDE IN A LANDING CONFIGURATION

“On a delta wing, the upper surface vortices break up naturally at high angle of attack, and a lift drop is observed on the parts of the wing affected by this phenomenon. This break-up may jeopardize the aircraft longitudinal stability (appearance of vibrations, buffeting), in particular at angles of attack higher than normally used for landing..”

The Sikorsky S-67 Blackhawk, 1970. Submitted to the US Army’s Advanced Aerial Fire Support System (AAFSS) program following difficulties with the Lockheed AH-56 Cheyenne.
The Blackhawk was put through a long series of tests from 1970 to 1974, breaking speed records along the way, but was ultimately judged unsatisfactory

“The AH-56 Cheyenne was a four-bladed, single-engine attack helicopter developed by Lockheed for the United States Army’s Advanced Aerial Fire Support System (AAFSS) program to produce the Army’s first, dedicated attack helicopter. Lockheed designed the AH-56 utilizing a rigid-rotor and configured the aircraft as a compound helicopter; with low-mounted wings and a tail-mounted thrusting propeller.”
In 1966, the Army awarded Lockheed a contract to develop 10 prototypes of the AH-56. The first flight occurred on 21 September 1967. In January 1968, the Army awarded Lockheed a production contract for 375 aircraft, based on flight testing progress.
A fatal crash and technical problems affecting performance put the development program behind schedule, resulting in the production contract being canceled on 19 May 1969. On 9 August 1972, the Army canceled the Cheyenne program. Controversy over the Cheyenne’s role in combat, as well as the political climate regarding military acquisition programs had caused the Army to amend the service’s attack helicopter requirements in favor of a conventional helicopter; viewed as less technical and more survivable…”

The giant Mil Mi-26 was featured on here yesterday, but the title of the largest helicopter ever built goes to the Mil V-12.
Work began on the V-12 (NATO reporting name “Homer”) in 1965, to meet a Soviet Air Force requirement to transport missile components to remote areas. The Mil Bureau used the main rotor, transmission and powerplant of their Mi-6 helicopter - mounting one set on a wing either side of the fuselage.
The first V-12 flew in 1968. All development was stopped in 1974. The V-12 never entered service due to various reasons. Both prototypes survive - the first in storage at the Mil helicopter plant in Panki-Tomilino, Lyuberetsky District near Moscow, the second prototype is on public display at the Monino Air Force Museum, also near Moscow.
