NK5500風(fēng)速儀在火箭學(xué)的應(yīng)用
火箭學(xué)是一門涉及火箭船的設(shè)計(jì)，建造和發(fā)射的科學(xué)。這些比賽在世界各地舉行，但是這些活動(dòng)不會(huì)在火箭的zui后一次發(fā)射中開始和結(jié)束。實(shí)際上，天氣和環(huán)境對(duì)火箭在火箭發(fā)射中的表現(xiàn)起著重要作用。借助諸如Kestrel 5500（NK5500)風(fēng)速儀之類的天氣跟蹤設(shè)備，我們將探索環(huán)境如何影響這些比賽，無(wú)論它們?cè)谑澜缟系娜魏蔚胤桨l(fā)生。

NK500氣象風(fēng)速儀記錄海拔高度和環(huán)境條件
火箭競(jìng)賽的規(guī)則之一是高度和環(huán)境條件的記錄。例如，一項(xiàng)挑戰(zhàn)是使火箭在一定高度的空中停留指定的時(shí)間。
由于高度是物體相對(duì)于海平面的高度，因此，除了簡(jiǎn)單地將火箭發(fā)射到空中之外，這項(xiàng)科學(xué)還有很多其他方面。海拔高度規(guī)則由以下某些規(guī)則指定：
高度計(jì)-必須使用市售氣壓高度計(jì)或GPS來(lái)記錄任何海拔競(jìng)賽。該設(shè)備的采樣率不少于每秒10個(gè)樣本，準(zhǔn)確率是記錄高度的3％或更高。
確定實(shí)際海拔高度-從機(jī)上海拔高度計(jì)或GPS記錄海拔高度。GPS平均海平面必須校正為高于地面海平面。設(shè)備還必須指出用于收集數(shù)據(jù)的衛(wèi)星數(shù)量。
范圍-比賽的目的是達(dá)到更高海拔。
用NK5500風(fēng)速儀測(cè)量環(huán)境因素
Kestrel 5500風(fēng)速儀是用于測(cè)量影響海拔高度的因素的理想天氣跟蹤工具。例如，溫度會(huì)影響火箭的飛行高度。這是因?yàn)樵谘谉岢睗竦娜兆永?，火箭的發(fā)射速度會(huì)變慢。飛機(jī)的起飛也可以這樣說(shuō)。
此外，空氣密度還受到您在世界各地的位置的影響。環(huán)境條件（例如高溫和高濕）與位置相結(jié)合，可以讓您瞥見成功發(fā)射火箭的過(guò)程。
使用Kestrel 5500，您可以測(cè)量溫度和濕度等元素。它也是跟蹤環(huán)境狀況的有效工具，因此您可以在訓(xùn)練或下一次比賽時(shí)參考它。
選擇NK5500風(fēng)速儀作為下一場(chǎng)火箭發(fā)射
您可以在NK5500風(fēng)速儀的幫助下將火箭發(fā)射的結(jié)果帶到月球。為下次火箭發(fā)射比賽選擇此設(shè)備，并親自體驗(yàn)完整的效果。 吉姆（Jim）是俄亥俄州高中火箭隊(duì)的教練，他幫助他的學(xué)生參加了一場(chǎng)全國(guó)比賽，該比賽包括全國(guó)800多個(gè)高中和中學(xué)隊(duì)。
“比賽一年四季都在進(jìn)行，挑戰(zhàn)每年都在變化。去年的任務(wù)是制造適合特定參數(shù)的火箭，該火箭將3個(gè)生雞蛋的有效載荷運(yùn)送到850英尺的特定高度，并進(jìn)行總飛行時(shí)間為43到46秒，參數(shù)緊張，比賽競(jìng)爭(zhēng)激烈，各支球隊(duì)在當(dāng)?shù)仫w行以取得資格，提交分?jǐn)?shù)，并且邀請(qǐng)前100名球隊(duì)參加在弗吉尼亞州舉行的全國(guó)飛行5月，比賽由航空航天領(lǐng)域的一些主要公司贊助，他們?yōu)閰⑴c者提供獎(jiǎng)學(xué)金，實(shí)習(xí)機(jī)會(huì)以及其他機(jī)會(huì)，隨后，優(yōu)勝者將與其他競(jìng)爭(zhēng)國(guó)際優(yōu)勝者，因此是一件大事。比賽旨在在全國(guó)范圍內(nèi)推廣STEM，并為學(xué)生展示機(jī)會(huì)。
我們的團(tuán)隊(duì)在俄亥俄州，因此我們?cè)诙具M(jìn)行大部分測(cè)試，這會(huì)產(chǎn)生與五月份在弗吉尼亞州所經(jīng)歷的天氣條件，溫度，濕度等完全不同的天氣條件。我們需要捕獲的天氣條件，以便我們能夠資格，然后我們需要預(yù)測(cè)并考慮決賽所面臨的大氣條件，這對(duì)于我們的成功至關(guān)重要。天氣條件之間的差異可能至少為100英尺或更多，并且團(tuán)隊(duì)始終位于目標(biāo)高度的幾英尺之內(nèi)，因此，對(duì)于所有事物，數(shù)據(jù)越多越好。去年我們進(jìn)入了決賽，但未能達(dá)到目標(biāo)，因此，今年我們正在通過(guò)收集每次發(fā)射的天氣數(shù)據(jù)來(lái)挖掘天氣因素，并且我們?cè)噲D基于從紅茶rel部門獲得的數(shù)據(jù)創(chuàng)建預(yù)測(cè)模型，以根據(jù)條件調(diào)整火箭。這是我們使用紅est的年，到目前為止，它正在幫助我們完成任務(wù)?！?/p>

Rocketry and Kestrel Meters: A Customer Use Case
Rocketry is a science involving the design, build, and launch of rocket ships. These competitions are held throughout the world, but the events don't begin and end at the final launch of the rocket. In fact, weather and the environment play a role in how rockets can perform in rocketry competitions. With weather tracking devices such as the Kestrel 5500 Weather Meter, we'll explore how the environment affects these competitions no matter where they take place in the world.
"My High School rocketry team needed a way to get accurate weather data to predict the altitude of their rocket. Kestrel gave us the perfect mobile solution that we bring to every launch! It provides us enough data points in a simple file we can import into a spreadsheet and calculate our altitude with a precision we never had before. The device has great battery life, accurate info, and is fully portable and easily set up. Well done, we are ahead of the competition and Kestrel has helped us."
-Jim S
RECORDING OF ALTITUDE AND ENVIRONMENTAL CONDITIONS
One of the rules in rocketry competitions is the recording of altitude and environmental conditions. For example, a challenge is to keep the rocket airborne at a certain altitude for a specified amount of time.
Since altitude is the height of an object in relation to sea level, there is much more behind this science besides simply launching the rocket into the air. Altitude rules are specified by some of the following:
Altimeters - The usage of a commercially available barometric altimeter or GPS must be used to record any altitude contest. The device much have a sampling rate of no less than 10 samples per second and an accuracy rate of 3 percent of recorded altitude or better.
Determining Actual Altitude - The altitude is recorded from the onboard altimeter or GPS. GPS mean sea level must be corrected to above ground sea level. The device must also indicate the number of satellites used to gather data.
Scope - The purpose of the competition is to achieve the highest altitude.
MEASURING ENVIRONMENTAL FACTORS WITH KESTREL
The Kestrel 5500 is an ideal weather tracking tool for measuring factors that affect altitude. For example, the temperature can make a difference in how high a rocket flies. This is because the rocket launch will be slower on days that are hot and humid. The same can be said for the takeoff of an airplane.
Furthermore, air density is also affected by where you are located in the world. The environmental conditions (such as heat and humidity) combined with location can give you a glimpse into a successful rocket launch.
With the Kestrel 5500, you can measure elements such as temperature and humidity. It's also an efficient tool for tracking the environmental conditions so you can refer back to it during training or the next competition.
CHOOSE KESTREL 5500 FOR YOUR NEXT ROCKETRY COMPETITION
You can take your rocketry results to the moon with the help of the Kestrel 5500. Choose this device for your next rocketry competition and experience the full effect for yourself.
Jim, the coach of a high school rocketry team in Ohio helps his students compete in a national contest that includes over 800 high school and middle school teams across the country.
"The contest goes on throughout the year and involves a challenge that changes every year. Last year the task was to build a rocket that fit into certain parameters that carried a payload of 3 raw eggs to a specific altitude of 850 feet and a total flight time of 43 to 46 seconds. The parameters are tight, and the contest is highly competitive. The teams fly in their local area to qualify, submit their scores and the top 100 teams are invited to the national fly off which takes place in Virginia each May. The contest is sponsored by some major corporations in the Aerospace field and they offer scholarships, and pathways to internships as well as other opportunities to the participants. The winner of the flyoff then competes for the international fly off against other countries, so it is a big deal. The contest is designed to promote STEM throughout the country and provide a chance to showcase possible career paths for the students.
Our team is in Ohio, and so we do most of our testing in the winter, which creates completely different weather conditions than what we experience in Virginia in May, temp, humidity, etc. We need to capture precise weather conditions so that we can qualify, and then we need to predict and account for the atmospheric conditions that we face for finals, which is critical to our success. The difference in weather conditions can be at least 100 feet or more, and the top teams consistently come within a few feet of target altitude so as with all things, the more data the better. We made it to finals last year, but fell short on our target, so this year we are digging into the weather piece by gathering weather data for every launch we do and we are attempting to create a predictive model based on the data we get from the Kestrel unit to tweak our rocket based on conditions. This is the first year we are using the Kestrel, and so far it is helping us in our quest."
