Aston Martin AMR23

[edgelo]

I really don’t get what that slides are for. I mean, what get the air so low for? Doesn’t the stream lose energy doing that excessive slope?

So a silly idea came to me. Would it be possible that at certain (high) speed, that stream breaks off the bottom of the “hole”, hits on the rearmost slope of the slide and go upwash over the beam wing or even the RW? In order to cause some kind of stall on the straights.

From looking at the picture posted above, it looks as though the slide has a kicker at the rear end, any air ‘trapped’ in the slide is going to have a lot of energy by the time it hits the beam wing.

Would that slide not act as an expansion and therefore slow the air and increase df? Yes at the beginning of the side pod, there is a constriction and therefore some lift but we a stahl, caused by the openings that we can absorbe.

A reminder to everyone but specially to the new people (welcome!).
The car threads are specially strictly moderated in this forum. Stick to this car and to hardware in the car threads.
Team politics and other team things, please in the team threads.
Lap times, happy faces, sensations and will they be faster/slower than XYZ, either in the team threads, in the testing thread or in the race threads.

If your post is in this thread and is not centering on this car, the physical car, it might have been or might be deleted or moved.
Let's keep the awesome car threads on this forum
a) focused on the hardware and
b) awesome.

Thanks.

does exist a clear view of the sidepod of the aston martin, wher the full "pool" that goes down and up is fully visible?

A new RW with a slightly backed/shaved off flap.

It also has a single centre support strut instead of a double.

Yup, that's true.

Front suspension layout.

One of the best pictures I’ve seeing to help visualize not only the water slides and how they feed the top of the diffuser, but also how the sidepods are sculpted:

I think its an illusion. It just slopes downward gently. That kicker seems to be where the exhuast manifolds are. Maybe some space to manage heat. So yes more of a lateral bulge than a downward slope?


I am not very impressed with the concept.
To me it's just a 2022 williams sidepod with dumbo ears that sheild the flow from the sides.

I wonder if there is some risk of starving the diffuser of flow energy?
No incoming air from the sides can add momentum to the air that expands and slows in the slide. Static pessure will be high, but low velocity.
Hard to judge if this is even significant, but i think the concept is just confused between Ferrari and Alpine. Where will the car work well and where will it do poorly?
Is it a top 3 car.
How much of the performance is in the sidepods.. is the rest of the car any good?
interesting times ahead!

You also said all last year the zero pods were a good idea so...

Why would the diffuser be starved? By that logic, RB sides are junk, but they are working more than fine, see bellow.

Static pessure will be high, but low velocity.

Exactly. Remember, high (or ambient-ish) pressure on rearward oriented surface is thrust, opposite of drag.

Hard to judge if this is even significant, but i think the concept is just confused between Ferrari and Alpine. Where will the car work well and where will it do poorly?

Sidepods are very significant if that's what you meant, demonstrated by so much work oriented towards them by all teams. The concept is hardly confused, but outsiders might be. It's very refined, bold and shows confidence of aero department. With Dan Fallows at the helm, I wouldn't discard that at all. It's quite clear what they are doing with outwash undercut, with extended lower inlet lip and also with the deep waterslide. I will save some of my views until after I get to do the simulation.

Impossible to tell anything about the floor performance of course, but it will be interesting to see Alonso in Q3 regularly.

[Blackout]

Alpine and Aston were 2 of the only teams that put their front brake caliper vertically at 3 o'clock in '22 (right).
But AM put it almost at 6 o'clock in '23 (left) probably to lower its CoG.

#AMuS reports that apparently the ground clearance of the RB19 is at least 10 millimetres below everyone else [based on what Mercedes observed]. And despite that, still no bouncing issues.


Toto says their floor would break if they would do the same.

#AMuS Another car with similar characteristics as the RB19 is the AMR23. Mercedes engineers claim to have noticed that the AMR23 drives at a lower ride height too, and despite that, gets over the bumps well. It is also strong on corner exit.

#AMuS The comparison with Aston Martin is interesting for Mercedes because they supply Aston Martin with the engine, gearbox and rear suspension.

Aston Martin only makes the front axle, which could indicate that this is where both the secret of Red Bull and Aston Martin lie.
