Nasa space shuttle flight simulator6/3/2023 ![]() ![]() Mark Kelly, who will command Endeavor's final mission, says sometimes mistakes happen. The run-through lasts for almost two hours and ends with a successful landing, despite the onslaught of problems.īut not every practice is perfect. The simulation is an exact mock-up of the flight deck that never leaves the ground - but shakes, rattles and rolls with some of the sensations of space flight. That's not good," one crew member groans, before the team coolly proceeds into a sequence of actions to conserve power and bring the simulation home safely. In this simulation, they kill one fuel cell and then another. He says the team's role is to come up with a script of possible malfunctions and deliver those malfunctions to the crew in the simulator with the tap of a button on a touch-screen computer. ![]() "We go in the office, and we'll say, 'OK, what do we want to do today?'" says Steven Messersmith, who directs the flight simulation team. Before then, members will go through hundreds of practice runs in a flight simulator at the Johnson Space Center in Houston. The command crew of Endeavor STS-134 is scheduled for lift-off in February 2011. What's next in human space flight for America is unclear. After 30 years, two tragedies and 130 successful missions that seemed to make space flight almost routine, the shuttle program is coming to a close. Hickey would run the whole simulation and, partnering with Nickel, the two would throw in problems that could happen in real life for the practicing shuttle commander to solve.Houston, we have a problem: The U.S. During training, Hickey would sit behind and between the astronaut on the left and the instructor on the right. This is just the real thing.”ĭuring training, Nickel would ensure the aircraft’s safety, and Hickey monitored the computer and played the role of a shuttle pilot informing the astronauts onboard. There’s just no comparison to being out in the real air, seeing the real landing aids. You get the real dynamics of real air going over the aircraft (and) you just can’t model that with a computer. With the engines in reverse thrust, you’re hanging in your harness. All you see out the window is dirt, there is absolutely no sky. ![]() In a plane like this, a corporate jet, there is no sky visible out of the front cockpit. “The shuttle has the flying characteristics of brick, basically, with wings. This is because there are no chances for a go-around as the spacecraft doesn’t have the atmospheric engines to gain extra thrust, so performing a perfect landing was crucial. The article said that the training aircraft was significant because, in the actual orbiter, commanders only got one chance to land the 110-ton spacecraft. In 2007, NASA published an article about what it was like to fly the STA, with the input of Jack “Trip” Nickel, a research pilot, and Alyson Hickey, a flight simulations engineer. Nearing the runway, if the pilots got the speed correct, a green light on the instrument panel would simulate a landing when the pilot’s eyes were 32 feet above the runway, mimicking the exact position a pilot’s head would be in a real landing. The right side of the cockpit had conventional controls and displays. The space agency said covers were retrofitted onto the left hand of the cockpit windows to mimic the view astronauts would have from the shuttle cockpit. In what was considered like “diving head first at a concrete strip six miles up,” according to NASA, the “landing pattern” of the spacecraft meant that the Gulfstream would fly at 300 mph during a dive, which is “several times steeper than that of an airliner.” Plus, flaps would be deflected upwards to decrease lift. NASA said that to match the shuttle’s descent rate and drag profile at 37,000 feet, the main landing gear was lowered, and the engine thrust was reversed. The STA was built to reverse its engines in flight and operated with two sets of main landing wheels. ![]()

Tomb of pope julius ii6/3/2023 ![]() ![]() Matthew torqued around its central axis.Ĭardinal Giuliano Della Rovere, who was elected Pope with the name of Julius II, invited Michelangelo back to Rome in 1505 and commissioned him with his funerary monument, a commission that would become the great sculptor’s torment for the rest of his life, “ la tragedia del sepolcro” (‘the tragedy of the tomb’), as Condivi called it. However, he only worked in the incomplete figure of Matthew before the commission was cancelled when Michelangelo left for Rome in 1505. ![]() Michelangelo was supposed to produce a total of 12 figures depicting the Apostles, destined for the niches of the choir of Florence cathedral. This work was commissioned to Michelangelo by the Arte della Lana (the wool guild) in 1503. Matthew, marble, by Michelangelo, 1505-1506, 271 cm height ( Galleria dell’Accademia, Florence). Michelangelo produced three works in the tondo form: his painting of the Tondo Doni, the Pitti tondo (see picture before) and this Taddei tondo. This work was also carved while Michelangelo was working on his David and was commissioned by Taddeo Taddei. Her turban and her top-garment which covers only one shoulder are less in accordance with the iconography of the Mother of God than with classical female figures. Mary is conceived of in an equally unusual way. John the Baptist, with his attribute of a baptismal bowl at his waist, into Mary’s arms, hardly fitting in with the characteristic image of the dignified redeemer of the world. The motif is a mysterious one, apparently using antique putti as models: Jesus runs away from the little bird held out by the infant St. This tondo is unfinished, but it is precisely its unfinished state which wonderfully reveals Michelangelo’s mastery in the sculptural details on marble. Madonna and Child with the Infant Baptist (Taddei Tondo), marble, by Michelangelo, 1504-1505, 82,5 cm diameter (The Royal Academy of Arts, London). In this work, Michelangelo seems to have been influenced by the lost cartoon of Saint Anne by Leonardo da Vinci, which was exhibited at the Santissima Annunziata church in those years. This work was sculpted in the same year in which Michelangelo sculpted his David, having found the time to dedicate to some other paid private commissions. ![]() The sides of the work are not polished, giving an unfinished character to the work, and accentuating this effect. In the background is barely visible a young Saint John the Baptist. The cherub upon Mary’s forehead symbolizes her knowledge of the prophecies. She also sits on a cube block, like Michelangelo’s Madonna of the Stairs. Thus the overall effect, despite the apparently playful attitude of the Child, is deeply serious, and the Madonna has an almost prophetic force because of her size, which bursts out from the frame of the relief. In this tondo Michelangelo placed, next to the stern Madonna with an open book on her knees, a Child whose pose recalls that of ancient funeral genii. This tondo was made for Bartolomeo Pitti, hence its alternate name. Madonna (Pitti Tondo), marble, by Michelangelo, 1503-1505, 85,8 x 82 cm ( Museo Nazionale del Bargello, Florence). Gregory were carved in collaboration with Baccio da Montelupo. Augustine, this sculpture and that of St. Pius, this sculpture was originally carved as St. Peter, this is Michelangelo’s most individual contribution for this Altarpiece, the intensity of Peter’s look and the way he clasps his garment can be seen as a study anticipating the Moses for Julius II’s tomb (see pictures below). He began working in this commission slowly and occasionally. On June 19th, 1501, young Michelangelo was commissioned with the sculptures for the niches of the Altarpiece. The Altarpiece was built between 14 by Andrea Bregno, with additions in the following decades. However, he was later elected Pope Pius III and buried in the Vatican. The Piccolomini Altarpiece was commissioned by cardinal Francesco Todeschini Piccolomini who wanted it for his tomb. Sculptures for the Piccolomini Altarpiece, marble, by Michelangelo, 1501-1504 (Siena Cathedral, Siena). ![]()

Shaft fonty6/3/2023 ![]() If part of the drive shaft were to snap, you’ll lose power to that axle in the best case scenario. While it is usually possible to drive with a bad drive shaft, it’s usually not very wise to do it for long. If your steering wheel is simply difficult to turn, you may need to take a look at the power steering pump. Obviously, this is a serious issue and it needs to be looked at right away. The tires will have a lot of resistance which you’ll be able to feel as you try to make a turn. If you try to make a turn with your vehicle and the wheels don’t turn immediately or they hesitate, then you have an issue with your drive shaft. You’ll need to have your drive shaft replaced because you can’t drive your vehicle in this condition. ![]() Either that or the u-joint itself is not stable. The cap seals of the bearings could have rust on them. If the U-joint of your drive shaft rotates too fast or fails to rotate, then it’s a problem with your drive shaft. It could possibly be out of balance or some other part of it could be worn out. If you’re driving and you hear a squeaking noise that is consistently coming from underneath your vehicle, then it is a sign that your drive shaft could be faulty. Often, this is a common symptom of a bad slip yoke. If you hear clunking noises in any of these cases, then it could mean your drive shaft has an issue and should be promptly inspected. When you accelerate your vehicle, do you hear a clunking noise? How about when you put the vehicle into reverse, or even into drive? Check your owner’s manual for the manufacturer’s recommendation. Note that vibrations that increase with speed may mean your tires need to be balanced. The worst part is that other drivetrain components can also be affected and damaged. It will get so bad that your passengers will be able to feel it too. If the problem is not fixed soon, the vibration will get more severe. These bushings are what normally keep the drive shaft from vibrating in the first place. The vibrations are likely due to worn out bushings of the drive shaft. This is usually the first symptom that people recognize when there is a drive shaft problem. If you’re driving the vehicle and you feel a lot of harsh vibrations coming from under it, then your drive shaft may be in trouble. More specifically, there are 5 common symptoms you can recognize that will let you know there is a problem with the drive shaft or slip yoke. When the drive shaft begins to have malfunctioning issues, then your driving ability will be impaired. The only way they can keep rotating quickly is if they remain weighted down and balanced exactly right. ![]() Since drive shafts rotate quickly, they’re able to move the rear wheels of your vehicle. This will depend on the manufacturer’s implementation of the four wheel drive or all wheel drive system. ![]() In the case of a four wheel drive or all wheel drive vehicle, you may find that it actually has two separate drive shafts: one for transmitting power to the front and another to transmit power to the back. A drive shaft (also called a propeller shaft) is essentially a long rod that is designed to transmit torque from the output shaft of the transmission to the rear differential in a rear wheel drive, four wheel drive, or all wheel drive vehicle.Ī drive shaft will often have internal splines on the end that connects to the transmission and a universal joint (U-joint) on the end that connects to the differential. ![]()

Clipping detector led6/3/2023 ![]() This will not bother most solidstate preamps but will add distortion on a few tube preamps. The input impedance changes from near infinity below 0.4V to a few dozen Kohm above that. If you light this LED with these amps they are already in gross clipping. The circuit can be easily set up to detect sine wave clipping from less than 1V to 30V peak-to-peak (i.e. A small output delay is added by C5 to allow detection of very short peaks.

The CLIP PG2 is a small and elegant wireless curtain-pattern PIR detector for indoor. I have also worked with Male Speech which can have consistent asymmetry but we rarely want to hear this LOUD and anyway a bit of clipping does not hurt speech intelligibility. While I have seen many single-sided transients they were only a half cycle and thus "brief", hardly worth knowing. It won't be an exact fit, but short clipping is fairly benign and extended clipping is bad- this gives you a clue. More to the point: it may turn-on with 1.2V steady, but brief musical transients may have to exceed 1.7V to discharge C1 enough to allow Q2 to turn-off.įor power amps with typical 1.0 to 1.2 Vrms rated sensitivities, this will approximately indicate "clipping".
