I like to think that there are still people visiting this thread who want a more constructive take on the conflict and are dissatisfied with the condition of this thread even if they happen to agree with the political bias. I acknowledge that I might be wrong about that. Certainly the discussion in portions of SDF degenerated to levels that I can not tolerate and participate in with good faith. But that's something I won't know unless I test the waters.
Air campaign during the Russian invasion of Ukraine - general characteristics
This is the timeline of combined losses for Ukrainian and Russia air forces since 24 February to 19 July. I used Wikipedia article on aircraft losses because I do have my doubts about Oryx in this instance. For example the recently added photo of a destroyed Su-35 from "29 March to 2 April" looks remarkably similar to the confirmed Su-35 downed on 3 April. Having spent some time analyzing the materials I'd say that Oryx is still mostly right and whatever duplicates are included account for the missing approximately 25% of losses that are confirmed by other reports and sources. On the other hand Ukrainian losses past March are completely not believable.
Quality might not be best but I had to downsize it so that SDF engine wouldn't make it completely unreadable.
Black numbers are downed aircraft. Purple numbers are aircraft destroyed on the ground. Red numbers are heavily damaged aircraft that returned to base.

I included the timeline counting days of operations which will help to establish periods of combat and consolidation. Remember that military equipment is designed to work in extreme conditions and has a limited life in combat conditions. For example when we consider the standard 8000 hours airframe life it is calculated per peacetime use. Once you add combat loads and reduce maintenance due to man-hours shortage the life of the airframe drops significantly below that number and requires additional repairs and maintenance afterward. This means that during wartime air force works in bursts. The first 2 weeks is the intended "high intensity" operations which are then followed by "regular" loads for the following 2 weeks. Then when should follow is an operational pause with low-intensity operations to maintain position but at the same time recover and consolidate your assets. Sometimes that is replaced by additional 2-4 weeks of fighting at "regular" loads which ten require longer recovery.
- High intensity phase involves contesting of airspace as well as ground strikes - it's when air supremacy/superiority is achieved and the target is primarily air force and air defense assets and command and control facilities along with key infrastructural targets to disrupt ground forces movements.
- Regular phase is focused on ground strike missions to degrade enemy ground force and strategic potential.
- Low intensity phase has reduced ground strikes and minimum air superiority missions.
Now compare it with Desert Storm which lasted only 5 weeks:

In terms of levels of activity reports indicate that Russian Air Force level of sorties never exceeded and average of 250-300 sorties per day in peak periods - that included air defense missions conducted over Russian territory. I haven't found out if those numbers included helicopter sorties.
This is a table of missions by category from USAF's Air Power Survey:
- AI - air interdiction
- BAI - battlefield air interdiction
- CAS - close air support
- DCA - defensive counter-air (shooting down aircraft)
- CAP - combat air patrol
- OCA - offensive counter-air (strikes against airfields)
- SEAD - suppression of enemy air defenses
- ESC - escort
- ESM - electronic support measures
- EW - electronic warfare (and recon)
- FUEL - refueling

If you compare the phases with the timeline of both operation you see similarities which are the direct consequence of logistical and mechanical constraints. The scale of air war in Desert Storm was
significantly greater than in Ukraine (close to an order of magnitude) but the general characteristics are preserved.
From what I can tell Russian invasion of Ukraine followed the extended plan - 2 weeks "high intensity" + 6 (rather than 2) weeks "regular" but it seems that it was slightly stretched over time so it lasted up to mid-April because of gaps in the preceding 2+6 weeks, probably due to weather. Then with the change of plan aka "second phase" of the invasion the low intensity phase began. However it involved regular strikes in the Donbas region for a period of 2-3 weeks in the end of April/early May. Low intensity phase lasted for close to two months which probably can be explained by preparations for resuming higher intensity when the counter-offensive begins. This is probably why we've seen an increase in activity in recent days. What we need to remember is that the machines are worn out from the intended use in the first high intensity/regular phase so they won't resume initial level of combat activity. It will be "high intensity" in character more than pure numbers matching the opening two weeks. That's something that can be noticed in statistics of all aerial campaigns throughout the history of combat aviation from WW2 onward. Every war is two wars: one against the opponent, another against physics.
Judging from well documented past precedent and whatever scarce data I could gather on current state of RuAF I think it has about 2-3 weeks of fighting in it, perhaps 4 weeks if they push it. Afterward it should collapse into a state of material "exhaustion" that will prevent it from operating above "low intensity" for several months - provided that recovery of fighting capability is conducted on terms of wartime mobilization. This prognosis of course assumes that Russia retains strategic reserve and doesn't wear it out in Ukraine. But Russia would have to be late-Third Reich insane/incompetent to do anything else and so far I think they kept the reserve intact. This is why Su-35S are rarely seen in action over Ukraine.
