Your Sunday Morning Jet Noise

Tu-160 "Blackjack":

Each time I see Soviet/Russian turbine engines, I'm amazed they haven't figured out how to reduce the smoke trails. Any thoughts on whether they are using water injection or are they just less efficient than Western counterparts?

A number of sources mention that the orangish smoke you saw here is a byproduct of the adding of nitrogen to the jet fuel. Adding nitrogen improves combustion, slightly improves power production and range, and reduces carbon deposits...it’s a variation of what Shell Oil does to their auto fuels, which is why they get slightly better performance/mileage from their V-power range of gas, and charge more for it. The result is what you saw here, but in a combat situation, simply substituting an unnitrogenated fuel would clear up the smoke trail.

The Soviet/Russian aircraft sure are prettier than their ships, I’d guess the aerodynamics force it.
