MAKS 2021's New Stuff (except Checkmate)
As spotlight is given for Sukhoi's Checkmate, other jet models are also revealed
Those can be "Paper-ware" in the future however, at least, we can figure out how Russians think about the future military aircraft.
Interesting thing is MiG-1.44 based Ship-borne aircraft
1) light-weight fighter - almost similar to trainer jet class like FA-50, Yak-130, Mako...but with IWB, EOTS?
More smaller than revealed 'Checkmate' (probably...), it reminds me a old German mock-up Mako. But compared to similar class aircraft, it has own internal weapon bays. Also splited leading edge flap is interesting point too.
RuAF will probably consists of their forces combination of Su-57 and Checkmate while this aircraft will target the export market. EOTS, IWB, and low RCS feature with small class hardware can appeal other nations.
However, it is a doubt that Russia can push two aircraft project smoothly.
There is no name-tag on this aircraft indicating MiG-1.45, but anybody can see this is coming from design of MiG-1.44. Basic configuration is kept while IWB, caret-inlet, low-RCS nose shape are applied.
They descripted this aircraft as Naval one but Next-Gen. Aircraft Carrier project of Russia is in doubt.
X-47B's planform with un-refined tail. Actually it is refined but it has very unusual internally canted tail and conventional nozzle. Compared to upper surface, lower surface of the aircraft is more unusual as we see center-line pod. Purpose of pod is unclear, but it can be gun pod.
Additional two small IWB are aligned; it is little bit unclear why pod is not made as attachment profile for big IWB.

MAKS 2021 - Su-35 Demo
As always, Maneuver of Su-35 is brilliant and fantastic
Additionally, Su-57 is also

LMFS Pic - [updated]
Long waited MiG's LMFS is coming?
General impression is mix of Boeing's X-32 and Northrop's JSF Concept while Russian keeps their side weapon bay for SRAAM.
ps. Thanks for beauty pic.s from JoannaRamira

8) Performance Chart
Ps, Fuel Flow, Specific Range (V/FF = m/s / kg/s = m/kg), Turn rate is described for the generic airliner DB. Due to the low resolution of sim, graph is very rough, but functioning of the program is checked.
9) Stability Chart
State Space maxtrix A, B and its eigen value is calculated by the SIM. Below shows test result for A matrix for longitudinal and lateral direction. Based on matrix value, exact controller design should be done in MATLAB or similar framework.

5) Airliner Trajectory - One-way Flight Simulation
Classic way of Flight-SIM, generic single aisle airliner DB is used to desribe 3t of fuel cruise.
6) Electric-Airliner Trajectory - One-way Flight Simulation
We assumed that previous DB's fuel-flow is not changing weight of fuel to describe an electric-airliner but with 1500kg power only.
7) Mil-Jet Trajectory - Range with Payload-drop and External Fuel Tank
With configuration of single aisle, external fuel tank and 2t of dropping payload are loaded and trajectory is tested. Dropping function, Range configuration, EFT function are working.
