But turbine engines are overhauled on cycles, not hours, and every engine start is a cycle.

In very simple terms this is because every start causes shock heating of the hot section components and every shutdown causes shock cooling. These stress the materials used which results in failures

it is simply not true in relation to fast jet engines - you are tracing both cycles and flight hours with split on work regimes - it means time of normal work, military power and afterburner work is noted separately and used for overhaul schedule establishing to make things more difficult also calendar is used to establish life limits for specific engine parts, and in fact does no matter if you are speaking about western and eastern engines of course there are nuances in a way of making calculations, methodology on west is much more flexible - especially in relation to newer generation of engines equipped in digital control and advanced health monitoring systems - but simple statement that western engines are in "on condition maintenance" is a kind of understatement

Russia says Ukraine was behind a drone strike on Moscow, but an expert is not conviced

Vladimir Putin blames Ukraine for the largest drone attack on Russia, but a warfare expert casts doubt on the claim and raises questions of a false flag strategy being deployed by the Kremlin.

Russia’s Use of Uncrewed Systems in Ukraine

Lacking in domestic-made, military-grade uncrewed aerial vehicles (UAVs), Russia has used cheap commercial drones and Iranian-made military drones in Ukraine.

They may not be keen on napalming their own country ?

How about a second option. Russia has used (I believe) a rocket launcher which is to all intents and purposes a fuel air weapon. If Ukraine have captured one or two of these they might not be so squeamish if they were firing them back at Russian forces.

Russia’s ‘Most Terrifying’ Weapon Seized By Ukraine; Turns The TOS-1A Thermobaric MLRS Against Invading Forces - Reports

One of Russia’s most terrifying weapons in the Ukraine war has been turned against its very own military. The Ukrainian armed forces have employed a captured Russian TOS-1A thermobaric multiple launch rocket system (MLRS) against the Russian forces. A video has emerged on social media showing a...

Are aerial incendiary bombs still a thing? When I watch vids like this from today where the AFU are clearing a tree line, it seems that napalming the tree line would do the trick more safely….

 

[Thumpalumpacus]

The Ukrainians are perhaps planning something similar. I hope the UAF has their logistics better sorted that the Wehrmacht did.

The Ukrainians are also facing very different opposing forces than did the Germans.

True. But given the apparent paper strength of the Russians it shouldn't be.

I'd imagine that even on the defensive, the Russians have logistical issues at least as large as the Ukrainians.

As I said in the first post I was keeping it simple and using a start cycle to move the aircraft to an new location was going to reduce the engine life.

Apart from afterburner and mil power time the same applies to most civil turbines. The engines on a long haul aircraft doing London Sydney with one intermediate stop are averaging well under 3 cycles per day and hours limited. The same engine on All Nippon Airways internal routes is doing over 12 cycles per day and is cycle limited.

Jazeera Airways (from Kuwait) used to be the masters of aircraft utilization, both in terms of time aloft and cycles. Some time around 2014, Airbus gave them a special award because they were averaging something like 14.7 operating hours per aircraft, with an average stage duration of something like 100 minutes.

Emirates' A380 fleet ops were also incredible. A couple years before the pandemic, one of their aircraft management guys told me that they were managing better than 15 hours per day across the entire A380 fleet.

It would have been higher, but they were still having some blade wear issues with their new Trent 900s, thanks to the hot conditions in Dubai leading to very long take-off rolls, combined with dust/sand ingestion issues. This was forcing them to swap out entire engines. Around 2017 or 2018, the GP7200 engines were getting more than double the average time on wing of the Trent 900s.

Unlike the Russians, the Wehrmacht was a formidible, experienced and well equipped force - *had* their Imperious Leader allowed his Generals to formulate and execute the necessary battle plans, instead of micro-managing as well as fixating on Stalin's name-sake, the Soviets would have been in serious trouble.

With Russia, there is just too much to list, as to why Ukraine is wiping the floor with their ass, but it harkens back to the Winter War and little Finland shredding the Soviets in a similar fashion: poor leadership, poorly trained troops, poor morale, poor logistics, poorly equipped, unreasonable/unrealistic goals and so on.

Speaking of Finland, In the mid-'50s, my next door neighbor in Frankfurt were the Paasonen family. Aladar Paasonen was instrumental in smuggling out Finland's intelligence equipment & records in Operation Stella Polaris. At the time he was working for the CIA in the I G Farben Building in Frankfurt.

That's because it can't penetrate high ground. It leaves a radar shadow. Basically it's line of sight. At least mine is.

I remember reading that a US airline, before deregulation, managed something like 600 flight hours in a month.

I wonder how well Russian command and control will handle the launch and early days of the UAF counteroffensive. Not well, is my prediction.
