Random Aerodynamic Oddity of the Day Thread

Why Engineers Steal from Nature

At the timestamp begins a discussion of when Frank Stephenson put a sailfish in a wind tunnel and what was learnt.

Silencing the air intake is one thing, but the second is potentially ecomodder friendly: Silencing the rear view mirror stalks with aeroform blisters with a 1:1.618 fineness ratio.

The Glickenhaus Mini Boot has [or was to have] a hypercar body with flying buttresses completely smothered with off-road paraphernalia.

Does anyone have a close-up photo of these blisters? Mclarin sells the mirrors, but apparently doesn't put the blisters on those they sell to "civilians". Or...do the blisters go on the car, not the mirror stalk?

It's you old friend the Aerodyamic Template[tm], as seen on the sailfish. A half-body of revolution, reduced to a wart on the stalk.

The only significant parameter is the fineness ratio.

Roof wing. but cab to does not slope either up nor down. Which is kind of odd, but I like that it's shallower in the middle and deeper at the corners, opposite of my roof wing but suspect it may delay vortices.

Oddly enough, Nissan's electric concept truck from 50 years ago was probably more aerodynamic.

Most certainly had a larger and more usable cargo bed.

Have they (SCG) ever made anything that looks like that rendering?

The Boot was developed by SCG, which also specializes in competing in the 24 Hours of Le Mans races and producing supercars. The benchmark was the Hurst Baja Boot off-road racing car, which was raced by Steve McQueen in the late 1960s.[1] Following on from this vehicle, the SCG Boot gained distinctive proportions with clearly defined wheel arches, wide-tread off-road tires and quadruple round headlamps set back in line with the windshield.

Don't know. I'd looked up The Boot and found the two year old rendering more of an oddity.

The Nissan pickups cab would fit well with a bed cap.

More on the Celera 500.

It's been a few hours since I watched it so I won't quote numbers, but according to...

The Design of the Celera 500L - Flying
Its circular fuselage is about 78 inches in diameter and 35 feet long and has the profile of a laminar-flow airfoil section (something similar to a NACA 67-018). The aft-mounted engine drives a...

...it's about the size of my home.

I think the bobtail appearance of the fuselage is due to the propeller which is smaller in diameter than the fuselage. To trust the laminar flow, I'd want an hydrophobi/oleophobic coating on it.

The German V12 is interesting, configured as two inline sixes on a common crankshaft.

Imagine if Otto and Jetopera had a baby prototype.

Makes me wonder how it would fare with a mid-mounted Honda CB 500 engine and RWD instead of the stock powertrain.
