NASA Sets Payload Record as Part of Parachute Development Test

Under a brilliant early morning Arizona sky, NASA conducted a successful, record-breaking test of a drogue parachute being designed to return next-generation space vehicles safely to Earth.

The 77,000-pound payload used in the test was dropped from the back of a U.S. Air Force C-17 at an altitude of 25,000 feet, setting a record for the heaviest single load ever extracted out of a C-17 during flight. NASA conducted the drop test, April 14, at the U.S. Army's Yuma Proving Ground near Yuma, Ariz.

The design load limit test will provide engineers with a better understanding of the full structural capabilities of the drogue parachute, currently under development for the Ares launch vehicles. The 68-foot-diameter drogue and all test hardware functioned properly and landed safely.

"Testing of a deceleration system is a very complicated process," said Ron King, Ares I first stage deceleration subsystem manager for the Ares Projects at the Marshall Space Flight Center in Huntsville, Ala. "All elements must work together in a carefully timed sequence to ensure a successful test. Through continued development and fine-tuning of the recovery system, our team is establishing a solid foundation for safe, reliable payload recovery."

The test team is managed by the Marshall Center and included engineers with ATK Space Systems near Promontory, Utah, the prime contractor for the first stage booster and United Space Alliance -- ATK's subcontractor, responsible for design, development and testing of the parachutes at its facilities at NASA's Kennedy Space Center, Fla.

This was the second in a series of three planned load limit tests designed to place the loads expected in flight on the parachute canopy. The next test series, called overload tests, will subject the parachute canopy to loads greater than what would typically be experienced in flight, to prove the parachute is strong enough to survive some degree of unexpected events.

A load limit test, as the name implies, pushes the parachute’s canopy to its designed limit -- supporting a 450,000-pound opening dynamic load, or force in pounds exerted on the parachute generated by the drag and pull of the parachute when it opens. The primary test objective was to deploy or open the parachute at a dynamic pressure of 420 pounds per square foot, simulating the opening load conditions the drogue parachute will experience when it is deployed to slow the rapid descent of the rocket's spent first-stage motor.

The complete motor recovery system consists of the pilot parachute, drogue parachute and three main parachutes. Similar to those used for the space shuttle boosters, these parachutes have been redesigned to accommodate larger, more powerful motors that will travel faster and fall from a higher altitude than the shuttle boosters.

All systems were go as engineers conducted last-minute checks in preparations for NASA's drogue parachute test. Image credit: NASA

The drogue parachute is the workhorse of the parachute recovery system, providing the initial deceleration and taking the brunt of impact as it slows the rapid descent of the rocket's spent first-stage motor.

As the test series progresses, engineers perform three classifications of testing: development, design load and overload. Each level of testing is intended to test the performance of the new parachute design with payloads of different size and weight, under varying conditions.

The U.S. Army's Yuma Proving Ground provides the test range, support facilities and equipment to NASA for parachute testing. The U.S. Air Force Flight Test Center at Edwards Air Force Base, Calif., provided the C-17 test aircraft and crew.

(2a)...interstellar travel not acceleration constant (laser)... a light´s beam that rotates is not a light´s beam that rotates... if it would be 1 only beam even the infinitesimal centrifugal force from gyration perhaps would break the beam launching tangentially its photons at straight line, as the stone of a sling loop that breaks. The arriving light (radiation) from a gyratory pulsar star is something seemed, the same than gyratory laser pointer from horizon to horizon 180º in 1 second, each beam that exits from a gyratory source is an independent light´s ray with limited length that only goes away in straight line: source on, beam starts; source turns, that beam finishes, is off, and starts-on another beam in the new direction... Photon, its mass "is believed" that is zero, but is the Photon´s Mass impacting against the future Space-Sail that produces the Transfer of Linear Momentum (mass*speed), the impulse... Photon, "relativistic" mass M = E/c²... constant h=6.626*10^-34 joules-sec... v, frequency e.g. red light=4*10^14 Hz... that photon energy E = h*v; E = (6.626*10^-34) * (4*10^14); E = 2.6504*10^-19 joules * (6.24*10^18 eV)=1.6538 eV... c=3*10^8 m/s, that photon MASS M = E/c²; M = (2.6504*10^-19) / (9*10^16); M = 2.944889*10^-36 kg... that photon "relativistic" Mass ~29 ten-sextillionth of kg ______ 4 semicircular-Screens, if it would be 1 only beam, infinitesimal centrifugal Force ((N=kg*m/s², we do reference to g-Earth in any Universe place, for that also on the Moon kilograms force=Newtons/9.8)) in kgf (kp) from that Photon, according to huge centrifugal G (kgf=kg*number of g´s)... radius Earth→screens, 1: 95493 km (96,105,971g)=2.8*10^-28 kgf (~28 hundred-thousand-quadrillionth of kgf)... 2: Moon 384,403 km (386,870,541g)=1.1*10^-27 kgf (~11 ten-thousand-quadrillionth of kgf)... 3: Sun, 1.5*10^8 km (150,962,873,002g)=4.4*10^-25 kgf (~44 hundred-quadrillionth of kgf)... 4: Andromeda, 1.9*10^19 km (913,135,316,143,368g)=2.7*10^-21 kgf (~27 ten-thousand-trillionth of kgf)... When source turns, each individual laser mark on the semicircular-screen (L=3.14*r) has zero speed, do not moves, arrives and it vanishes, such as a light-bulbs row that they go being on and off one after another, from the first to the last hyperluminal speed, but is Not the speed of a mobile because there is Not any mobile.

...interstellar travel constant acceleration (katherine Coleman Lowe ,,,"Goble" "Johnson" the unique Hallelujah that it is to listen changing its meaning is the Handel with Mozart´s arrangements)... the anglo-american daughters still have another vindication silenced by religion: Surname Father + Surname Mother... sons too, or the Mothers do not count in their Right to put her surname to her daughters and sons. Women besides suffer the religious-imposes-humiliation lose her surname each time that get married and "change" to the her husband, how if woman could be a merchandise of his property doing Lose to Wife as Person Her Identity, something impossible that husband could accept for himself; multicredos-religious humiliating to the women how religious can, deceiving to Innocents with religion-tale. Women Intelligent and Innocents so accustomed by the religious to down the sight that to her the trees prevent to see the forest, incapables to see the lie that religion is. USA thanksgiving?, forever and ever "blessing" the table?... professional-religious out from the World once and for all

...interstellar travel constant acceleration (Katherine Coleman Lowe ,,, "Goble" "Johnson", the "girl" math genius who went across the History Doors for enter in the Legend)... her teachers to the parents when still she was a prodigy child: "in all my years of teaching I´ve never seen a mind like the one your daughter has, you have to go, you have to see what she becomes...", "tell me where you want that it fall on the ocean and I will tell you from where you have that launching it", she said to the NASA scientists when the first astronauts, to who were go the life in it, did say "let´s get the girl to check the numbers"... "The little airplane that fell from sky", nobody knew why then, she discovered and demonstrated mathematically that was been the vortexes of tip-wings from a big airplane that was preceded to it flying some higher, that turbulence from other tip-wings made that little plane would crash. And till today that Aeronautics knows it that Katherine discovered (the newspaper gave the news let alone her name as author). But as she was woman and black, they merit adjudicated to her department in chief and she was let as an assistant. And so many discoveries and orbit calculations that she made for do go and return with security to the Apollo program of the Moon, she carried to them literately of her hand. To Katherine Johnson they requested the Moon and she do not stepped back, with little more than a pencil, a slide rule and an incipient data processing, that she had that verify, traced with precision the trajectories that woul permit the landing... "NASA never will forget her enthusiasm indomitable spirit and leadership, and the achievements that we do not could have reached without her"... "the Frenet trihedron, the orthogonalization algorithm I prefer it over Euclidean coordinates", wonderful Analytic Geometry, branch of the Geometry that represents geometric figures, flats or tridimensional, through equations and situates them in the coordinates axes x,y,(z)... Katherine and the elliptical orbits "10,000 cosine calculations": e, eccentricity >0 and <1; e=cos B/cos a... ellipse, if it is defined as closed curve of intersection of a plane that cuts to a cone without pass by its vertex nor its base; a, angle of the cone between its axis and generatrix; B, angle >a and <90º between the plane and axis or height of the cone... The exact point go/no go when still had not formula for know where it was, because would be her who would invent it: "...looks at the problem numerically and not theoretically...Euler´s method..." (was not the same fall on anywhere place of the steppe when Yuri asked to that amazed old woman was where a phone to call and would come recover to him, that have a ship just aside)... "Katherine have a got at it"...the Katherine´s answer: "the point go/no go of the reentry, that is to pass from the elliptical orbit to this exact parabolic trajectory, with this latitude and longitude of capsule fallen on the ocean, give up ot take 52 km²"... "I like her numbers", said Glenn, "if she says they´re good I´m ready to go"... (When someday a functionary went to ask chief for those works, this said "look you speak with Katherine because in reality she makes almost all"). Do not find strange in a country where its religious presidents say that of "God bless to the United States of America" (and to the rest of the World that crack to it a ray). Although belated, finally from 2015 recognition of NASA and nation: Presidential Medal Freedom, and in Langley "Center Katherine G. Johnson", and Gold Medal of Congress. (Her scientific publications: Wikipedia Katherine Johnson (12)... Legendary Mathematician Katherine Coleman Lowe: Honor and Glory Eternals... Already must have in the Universe one star called Katherine.

...interstellar travel constant acceleration (marine ghost wave)... it would form, besides sum little waves, por la Cizalladura entre Dos Fuertes Corrientes Marinas que de repente cambian de dirección Enfrentándose, la fricción entre moléculas de agua que chocan de frente provoca el súbito alzamiento de la rarísima ola fantasma aun hasta 30 mts de altura, detectadas ya por satélites. Fricción contra fondo costa, ola normal y de tsunami; fricción de cizalladura entre corrientes oceánicas, Ghost Wave wall of water que aparece en el frente de colisión y desaparece a continuación naufragando, con fuerza max al romper la ola, barcos enormes (München) "sin explicación"...

...viaje interestelar aceleración constante (fricción molecular)... eso es la Fricción en primera y última instancia, interacción de fuerzas electromagnéticas entre moléculas. La malla de electrones orbitales que las recubre hace que, si están separadas, al chocar de forma natural hasta una determinada fuerza las moléculas reboten, 2H2 + O2 (sin más no pasa nada) = 2H2 + O2)... si se induce un choque más violento de ese límite se altera la composición de las moléculas y hay transformaciones químicas, 2H2 + O2 (+ chispa=boom) → 2H2O. La Tierra vista desde Júpiter, la Luna parece unida pero al acercarse Tierra y Luna son ínfimas en comparación con el inmenso espacio vacío que las separa. Eso es la Materia, sobre todo espacio vacío, moléculas con sus átomos de núcleos atómicos con sus protones y posibles neutrones, por aquí, unos electrones en órbita por allá y las Fuerzas Electromagnéticas (fotones) actuando a traves del relativo inmenso espacio vacío. Fricción entre dos objetos = fuerzas electromagnéticas entre las mallas de electrones orbitales de los átomos de sus moléculas.
