papl doust !

Three times faster?

Hmmm, with a turning radius defined by tens of miles.
Read sometime about how the S-71 handled at high mach.

High mach means high altitude, which mean little atmosphere for controls.
Your aircraft will not be doing high mach at low altitude and if it goes high it will be looking for a filling station or airstrip.

The Me163 once its fuel was spent was a threat to no one. Your aircraft cannot carry enough fuel to be a threat except maybe on a one-way such as the 163s did.
The smaller an aircraft the more susceptible it is to damage from cannon fire or a missile warhead.
The small Mirage fighters in the Falklands suffered the same fate your aircraft would.
Destroyed aircraft, dead pilot.

The F-106 had extremely long legs at a high speed cruise, over three hours, yet at continuous Mach 2, twenty minutes and you had better find a tanker now.

Let’s see yours has an eight minute throttled rocket?
Does such a rocket exist?
How much space does it take?
How much does it weigh?
Where will you put internal fuel for the jet?
Where will you put weapons?
External weapons greatly limit airspeed, internal weapons need sub-systems to lower and retrieve launch rails. System must be capable of expanding and contracting due to temp. changes with out binding or causing loose slap.
Such systems are heavy.
A cannon with enough rounds not to be just an after though will weigh around a 2,000 lbs. with cartridges.
Where will you put it.

Your reclining seat.
Go sit in a chair that reclines as far as yours is supposed to and try to look over you shoulder.
You cannot.
The reclining pilots seat seems like a good idea until real world physics and how the human torso functions are considered.

If you want to check into ejection capsules read up on the B-58 Hustler and F-111.
They had capsules and an a airframe large enough to carry them.

High speed ejection is easy to talk about but in the real world is a fifty-fifty proposition at best.
An aircraft with high-speed system has to be large to handle the superstructure involved and as they found out with the F-106 system, they require more sub-systems which increases the possibility of a sub-system failure, and a dead pilot.

A twenty millimeter cannon would chop your aircraft into small pieces in short order.
F-86 pilots in Korea said that the Russian 37 mm cannon could destroy a Saber with one round and a Saber was larger and made out of metal more able to withstand cannon fire than your aircraft.
Metals withstand projectiles not by being stiff like cast iron but by bending like mild steel.
Modern alloys create, in a way, the solidity of iron with bending of soft alloys.
Any metals that would break into pieces like a carbon fiber composite does, is worse than worthless.
Metal is still heavy in the amount required to protect a pilot from the rear.

If you do a net search you will find several instances of where an F-106 in an air to air collision lost the entire nose from the base of the windshield forward, yet the pilot safely landed the aircraft.

What would happen if your aircraft suffered such an incident, beyond the probable funeral for the pilot?

The U.S. Air Force had an official edict–SPEED IS LIFE.
Another would be– Size capable of withstand heavy damage and continue to fly is life.

Yours is a flying coffin.

Thank you for your thorough answer.

I set the parameters on this in a finnish defence site. Little by little this has become bigger.

It does not mean that a better far more capable aeroplane with a higher pricetag wouldn’t offer more capabilities.

You are right about the rockets…they possibly burn just 2-3 minutes..I figure 250 kg per unit for them..preferably just 150-200 kg. They ought to be reusable with fast reloading. I have no idea if this is a good idea…but seems that a AB fitted turbofan burns too much gas and limits the air time drastically.

This concept could cruise with turbofan neatly at 800-1100 km/h depending of the altitude and if a situation hits on…then boost is used to go to anywhere in 2-3 minutes..I mean up to 24 km at least.

My concept totally rejects the possibility that this could be an underdog in any 1 to two situations. Therefore it is lite..and agile and fast + stealth…and thus small too.

The mach 3 is not needed..the clim rate of 280 m/s is quite enuf..if you climb to meet someone at that rate in 45 degs angle you’ll be possibly goin just over mach.

To intercept a hostile that goes mach 2.4 at 21 km you don’t need to go mach 2.5 yourself.

Also this is very fragile easily..concealed missiles and fuel are all just centimeters of each others. BK27 is very lite cannon and with 150-200 rounds it don’t weigh over 1200 lbs.
