The pilot of the crashed MiG 27 jet was reported to be safe.The MiG-27 is a variable-geometry ground-attack aircraft, originally built in the Soviet Union and later licence-produced in India by Hindustan Aeronautics as the Bahadur (Valiant").
Also, the twin variable-geometry turbochargers were replaced by a single Honeywell unit mounted near the right-hand exhaust manifold, and it draws from the left-hand bank via a flow-optimized tube at the back of the block.
Under the off-design condition, to avoid entering the unstable working state and ensure enough operating performance requirements, the variable-geometry compressor technology has become the mainstream.
Meanwhile, the 718 S features a 2.5-litre version of the same engine, but with variable-geometry turbocharging(like the 911 Turbo), producing 345bhp and a mighty 420Nm of torque = 0-100 kph in 4.2 seconds!
It features a variable-geometry turbocharger, and is SAE-certified at 181 horsepower and 369 lb-ft of torque at 2,000 rpm.
Despite all this, CO2 emissions have fallen to 99g/km from 104g/km and combined economy has gone up from 70.6mpg to 74.3mpg, thanks largely to the adoption of a variable-geometry turbocharger and low-rolling-resistance tyres.
The Tu-160 Blackjack is a supersonic, variable-geometry heavy bomber, designed to strike strategic targets with nuclear and conventional weapons deep in continental theatres of operation.
Because the variable-geometry wing requires mechanisms that add considerable weight, it isn't considered ideal for most combat aircraft and today's newer warplanes don't use the feature.
The economy is achieved because, for most day-to-day driving, including motorway cruising, the variable-geometry primary turbocharger does all the work, while the smaller, secondary turbo is dormant, saving energy and improving efficiency.
The Council envisages the creation of "variable-geometry groups of member states," which would cooperate in joint construction activities.
The Air Force was on the way to producing a ponderous aircraft with a variable-geometry wing--an updated F-111--that, in turn, Congress would almost surely have refused to authorize.
The latter no longer feature the complex variable-geometry, a la Concorde configuration of the earlier missile, but their shape is classified, hence the strapped-on block ahead of them on this photograph.
