2024 Pre Season Testing Guide

Flow-Vis

A fluorescent powder that is mixed up with a light oil, usually paraffin, and is painted liberally on to the car

Then when the car goes out and as it’s moving up to speed and going through a cornering condition, the paint dries as the oil evaporates and you end up being able to visualise, very clearly, what sort of flow structures you've got.

Sometimes flow-vis will just be painted on a small portion of the car, to observe the airflow in a particular area, but sometimes you’ll see cars covered in flow-vis

Aero Rakes

A series of ‘pitot tubes’, which are sensors designed to measure the airflow off of the body structures.

By measuring the dynamic pressure, they can get an idea of the flow structures that are coming off things like the front wing, and the front wheels

There’s a whole host of different shapes of aero rakes, some quite tall, some very wide and some (like the Ferrari below) which look particularly interesting.

Watch out for

Lap count - I personally think this to be far more important than lap times. If a team can get undisturbed running for the 3 days it’ll be ideal.

High winds - this is common with the Bahrain circuit, and it’s a good chance to see how the cars handle under less than ideal conditions.

Team/driver behaviour - the teams behaviour and body language can always be an interesting thing to observe, especially in regards to car performance.

Personally I don’t read too much into lap times themselves because you don’t know how much fuel cars are carrying or what engine modes they are using. I find testing more interesting to have a look at how the cars handle and also to observe body language.

Schedule

Each day will be split into 2 sessions (so over the course of the test there’ll be 6 sessions all together)

The track will open for running from 7am GMT until 11am GMT for the morning session

The afternoon session will run from 12pm GMT to 4pm GMT

The teams will announce their driver split in due time

How to Watch NASA’s X-59 Quiet Supersonic Plane Roll Out of the Hangar 🔥 4 o’clock Eastern time!

Is supersonic passenger travel in the future? It looks like it might be.

Supersonic flight happens when a flying object exceeds the sound barrier: 767 miles per hour (1,234 kilometers per hour), or Mach 1. The first person to break the sound barrier in a plane was Chuck Yeager in 1947. Yeager made his famous flight in the Bell X-1, one of the first experimental aircraft, also known as X-planes.

As most of you know, the SR 71 was famous for its double sonic boom. Personally, I did not find the noise offending. But the office at Beale AFB, CA, used to get complaints varying from framers saying that their chickens wouldn’t lay eggs to their windows being broken!

NASA used the SR 71 in tests in the 1990 to prepare for today’s unrolling of the new X 59. The SR-71 was used in a program to study ways of reducing sonic booms or overpressure that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound.

Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the “peak” overpressures of sonic booms and minimize their startling effect on the ground.”

Among the significant experiments flown with the NASA SR-71s, there was a laser air data collection system that used laser light, instead of air pressure measured by pitot tubes and vanes extending into the airstream, to determine airspeed, angle of attack, vertical speed, and other attitude reference data.

The aircraft will be rolled out of its hangar in Palmdale, California, at 4 p.m. Eastern Time on Friday. You can watch live on NASA’s website and YouTube (embed above). And while the aircraft’s first flight is probably still a ways off—fingers crossed we get more details on the timing during Friday’s ceremony—this will be a first look at the needle-nosed aircraft in all its red, white, and blue splendor. Leaders from NASA and Lockheed Martin are slated to speak at the event. Linda Sheffield of Habubrats.

Got any cool albatross facts? I love them they are so cool and large

It’s a bird, it’s a plane, it’s—

Honestly kind of both?

An albatross is honestly a complete weirdo of a bird that seems more akin to a sci-fi cyborg drone than a real earth animal.

firstly, there are the wings. Albatross fly incredible distances, able to span the length of entire continents without a single flap if they choose to and the winds are favorable. Their shoulders have a specialized tendon that locks them in the open position while fully extended, this means they aren’t using any energy or straining their muscles from being in the same position for hours on end.

In addition to having an excellent sense of smell, an albatross has a very impressive nose in general. Specifically, they have complex tubes which allow them to measure exact air speed in flight as a pitot tube would. What units does an albatross measure speed in? That I could not tell you.

They are also hopeless romantics which mate for life and bond through complex courtship dances unique to each pair. They only raise one egg per breeding season and devote themselves fully to raising the chick. This behavior has made most of the albatross species become endangered as Europeans introduced rats and feral cats to their breeding grounds, though their main threat is fishing.

Obsessed with these DC-9 diagrams in this station number booklet. They're such silly creatures and I love them.

When working on aircraft mechanics have to use these "station numbers" in our logs to provide exact references to certain locations on that aircraft. They're typically expressed in "inches from the datum" which is an imaginary 0 point the engineers of the aircraft came up with that typically starts at the nose or firewall, or a few inches forward of the nose (I have a theory it's where the prototype's test pitot tube would have stuck out to) it varies from aircraft to aircraft. Datums also get kinda weird with ultralights/light-sports/taildraggers (the Ultra Pup I'm trying to fix up starts in the center of it's forward landing gear), but they're super important in calculating the weight and balance/Center of Gravity of aircraft.

To me planes are basically just very very large horses that can fly. Catch me standing under the nose cone trying to feed apple slices into the pitot tube

Black-and-Yellow Mud Dauber (Sceliphron caementarium)

As far as wasps go, these mud daubers tend to be a fairly peaceful species and can be cautiously observed without issues. They are a widespread species, found throughout North and Central America, South Africa, the West Indies, the Mediterranean basin and on select Pacific islands. They occupy a wide range of habitats, natural or manmade.

The mud dauber owes its name to its mud-sculpting capabilities. The female wasp collects mud at the edge of pools of water, which she shapes into a cylindrical cell and hides in a shaded area. A nest can have up to 25 cells arranged vertically, altogether around the size of a human fist, which are then coated in another layer of mud in order to give the nest a smooth, uniform appearance. The wasp then goes out and catches spiders, which she paralyzes and stores inside the cells in order to feed her brood. An egg is deposited on each prey, which will be eaten at as the larva progresses through its development. The brood only emerges from the nest as full-fledged adults. Adults typically feed on nectar, especially that of parsnip flowers.

These wasps are solitary and mainly peaceful, and thus stinging is rare unless they're bothered or their nest is approached. Though mostly harmless, they can be occasional pests due to their habit of building nests on man-made structures; in fact, a black-and-yellow mud dauber's nest was responsible for a plane crash in 1996, when a wasp nest lodged inside the plane's pitot tubes caused the pilot to receive incorrect airspeed information. Unfortunately, 186 people died as a result of this crash.

think i started cryng because i thought about air getting trapped in a pitot tube and being stuck there forever

standing at the fence with my little point-and-shoot next to these grizzled planespotters with massive telephoto lenses was so humbling 😭 i lost the pitot tube measuring contest today

With all the parc ferme rule changes with this new format, what would happen if it rained? Are they allowed to make changes for the shooutout (or whatever it’s called) in that case? I don’t actually know what the procedure is even if it wasn’t a sprint weekend but I imagine it’s more complicated now that there are two qualifying sessions.

The rules around parc ferme always relaxed if weather changes after qualifying so if there was a dry qualifying and then the race or the sprint shootout was wet parc ferme rules will be relaxed so that required set ups changes can happen whether that’s change brake ducts and radiator ducts to reduce or increase cooling and alter the pitot tubes used for measurement. They can also change the headrest around the driver, as there are three different types suitable for three different temperature ranges.

Similarly if there was an incident in the sprint the car can be repaired before the race without breaking parc ferme as long as the team replaces the parts with ones of the same specification and doesn’t change the actual set up of the car.

P-38 by Willard Womack Via Flickr: Ready to go fly, parachute and all. But, the cover has not been removed from the pitot tube. Its primary purpose is to keep dirt / mud, daubers from building a nest inside the tube.
