News item on new project from TsAGI in Russia for a short haul rear engine airliner project. It has the engines situated above the trailing level of the wing.

New airliner being developed by TsAGI: No comparable global counterparts
22 May 2015

In May, scientists of the Central AeroHydrodynamic Institute (TsAGI) completed the first phase of research of a promising short-haul aircraft model. This new-generation airliner has been designed by TsAGI under the Federal Target Program “Development of Civil Aviation in 2002-2010 and for the period to 2015.” The tests were completed in the transonic wind tunnel of the Institute.

The future aircraft does not have any similar counterparts in the world, and is distinguished by two major innovations. The first innovation introduced by TsAGI’s specialists is a small degree of wing sweep which ensures laminar flow with no random velocity and pressure fluctuations on the surface, and significantly reduces aircraft resistance. The use of modern profiles allows keeping the same speed as that of predecessors — 830-850 km/h.

The second distinguishing feature of the new aircraft is the location of the engines over the rear edge of the wing. The scientists chose this placement to reduce the noise from the aircraft flying over areas adjacent to airports. This environmental requirement is becoming constantly more strict and is one of the main criteria for the development of advanced aircraft. In the new layout, the noise from the power plant fans, being the main source of sound, is reflected by the wings upwards before reaching the ground. Furthermore, this solution allows installation of more efficient engines with a larger diameter. Moving the engine to the top reduces the likelihood of foreign objects being ingested into the intakes from the runway, which increases safety. This engine position makes it possible to reduce the length of the landing gear, thereby making the design more lightweight.

“The tests have confirmed our estimates in terms of speed and efficiency,” stated TsAGI’s head of the department of aerodynamics of civil aircraft prospective layout Ivan Chernyshev. “We will recommend this layout for greater technical evaluation by the domestic aircraft design offices.”

Hi,


here is some ideas from Institute Zhukovsky for future aircraft,my friend Skyblazer displayed
one of them before.

Third post:

Image 3: Study for a replacement of the An-2 and L-410. All weather capability, rough field capability, safety and fuel economy are priorities. 15-19 seats. Conventional version in development.

Image 1: Same basic requirement as above. Conceptual version with twin engines mounted in the tail driving a contra-rotating prop. Engine placement allows reduced noise for passengers and those on the ground, while providing better performance in case of an engine failure.

Image 2: Flying wing (really BWB in modern Anglophone terminology) airliner with 180-200 seats (competing with larger airliners rather than super-capacity airliners). M=0.8, 20-25% more efficient than conventional.

Image 4: Business jet "tadpole", 3-6 passenger. Large cabin for comfort with minimum aircraft size for efficiency. Aerodynamic optimisation.

The link for post #3 is broken.

Post #4 are NewFACE projects. The photos for the article were taken by TsAGI... but the projects are not theirs.

Does anyone have information on post #6, image 2, left-hand aircraft? It looks to be one of the 15-19 seat studies mentioned earlier... but with remotely driven props in the tip vortices and some kind of leading edge devices?? Looks very interesting.

From Авиация и Космонавтика 2018-12,

here is a testing in TsAGI for a swept wing concept with 35 degree.

This was testing for the La-160. The article says exactly that. Not a TsAGI project.

Yes,I didn't say it was from TsAGI design or project,it's here.
