Berkut Aircraft - It retained some of the systems and component designs from the Su-27 (the all-weather supersonic fighter aircraft with Nato reporting name Flanker), for example, the design of the canopy, landing gear, some of the avionics, and the near-
vertical tails. Very few Berkut's go up for sale regularly, so it's very hard to know what the "current" price would be. However, given what others have sold for in the past, and assuming that it's a decent plane in good shape, that's NOT an unreasonable price in comparison.
Berkut Aircraft
Compared to a swept-back wing of the same area, the swept-forward wing provides a number of advantages: higher lift to drag ratio; higher capacity in dogfight maneuvers; higher range at subsonic speed; improved stall resistance and anti-spin characteristics;
Forward-Swept Wings
improved stability at high angles of attack; a lower minimum flight speed; and a shorter take-off and landing distance. I only know of one Berkut project for sale, and last I checked it was about this price.
My understanding of that particular project (and I do NOT know if it's the one you're talking about) is that you should avoid it like the plague. The forward-swept mid-wing gives the Su-47's unusual and characteristic appearance.
A substantial part of the lift generated by the forward-swept wing occurs at the inner portion of the wingspan. The lift is not restricted by wingtip stall. There are lots of Long-EZ's for sale and given the relative performance of the two aircraft, the price premium for the Berkut (to me) is absurd.
I've flown both (and worked on both) and while the Berkut's a nice enough plane, there are many things about it that are worse than the Long-EZ, as well as a few that are nicer. Now, for an O-540 Berkut, maybe the added performance is worth the price - I know folks that cruise cross-country (east coast to west or vice versa) in daylight at 22K - 25K ft.
- but still, I don't see it for the O-360 Berkuts. The length and a fan tip diameter of the engine are 3.98m and 1.05m respectively, while the dry weight and delivery weight of the engine are 1,550kg and 1,712kg respectively.
The engine also features a thrust reverser and a low-pressure compressor. The ailerons – the wing's control surfaces – remain effective at the highest angles of attack, and controllability of the aircraft is retained even in the event of airflow separating from the remainder of the wings' surface.
Maximum turn rates and the upper and lower limits on airspeed for weapon launch are important criteria in terms of combat superiority in close combat and also at medium and long range, when the mission may involve engaging consecutive targets in different sectors of the airspace.
Are you talking about the Berkut project on Barnstormers.com posted Feb 9th? Actually $45K for that doesn't sound too bad for that project. I imagine it could be completed for another $30K to 45K depending on engine so you have less than $100K in it.
I agree with Marc, though, you can buy a nice, flying Long-ez for $40-45K. $100k to $150K for a flying Berkut is paying a lot to get there 20 minutes faster. The aircraft is equipped with a new ejection seat and life support system.
The variable geometry adaptive ejection seat is inclined at an angle of 60°, which reduces the impact of high G forces on the pilot. In May 2002, Sukhoi was selected as prime contractor for the next-generation Russian PAK FA fighter programme.
The PAK FA fighter aircraft is a development of the Su-47 but without the forward-swept wings. The first flight test of the PAK FA fighter aircraft was completed on 29 January 2010.
