NK5500风速仪在火箭学的应用

火箭学是一门涉及火箭船的设计,建造和发射的科学。这些比赛在世界各地举行,但是这些活动不会在火箭的zui后一次发射中开始和结束。实际上,天气和环境对火箭在火箭发射中的表现起着重要作用。借助诸如Kestrel 5500(NK5500)风速仪之类的天气跟踪设备,我们将探索环境如何影响这些比赛,无论它们在世界上的任何地方发生。

“我的高中火箭队需要一种获取准确的天气数据以预测火箭高度的方法。Kestrel为我们提供了完美的移动解决方案,我们可以将其带入每次发射中!它在一个简单的文件中为我们提供了足够的数据点,我们可以将其导入电子表格,并以前所未有的精度计算海拔高度。该设备具有出色的电池寿命,准确的信息,并且具有完全的便携性和易于安装的功能。做得很好,我们在竞争中处于领先地位,而Kestrel为我们提供了帮助。”

 NK5500风速仪在火箭学的应用

NK500气象风速仪记录海拔高度和环境条件

火箭竞赛的规则之一是高度和环境条件的记录。例如,一项挑战是使火箭在一定高度的空中停留指定的时间。

由于高度是物体相对于海平面的高度,因此,除了简单地将火箭发射到空中之外,这项科学还有很多其他方面。海拔高度规则由以下某些规则指定:

高度计-必须使用市售气压高度计或GPS来记录任何海拔竞赛。该设备的采样率不少于每秒10个样本,准确率是记录高度的3%或更高。
确定实际海拔高度-从机上海拔高度计或GPS记录海拔高度。GPS平均海平面必须校正为高于地面海平面。设备还必须指出用于收集数据的卫星数量。
范围-比赛的目的是达到更高海拔。

用NK5500风速仪测量环境因素

Kestrel 5500风速仪是用于测量影响海拔高度的因素的理想天气跟踪工具。例如,温度会影响火箭的飞行高度。这是因为在炎热潮湿的日子里,火箭的发射速度会变慢。飞机的起飞也可以这样说。

此外,空气密度还受到您在世界各地的位置的影响。环境条件(例如高温和高湿)与位置相结合,可以让您瞥见成功发射火箭的过程。

使用Kestrel 5500,您可以测量温度和湿度等元素。它也是跟踪环境状况的有效工具,因此您可以在训练或下一次比赛时参考它。

选择NK5500风速仪作为下一场火箭发射

您可以在NK5500风速仪的帮助下将火箭发射的结果带到月球。为下次火箭发射比赛选择此设备,并亲自体验完整的效果。 吉姆(Jim)是俄亥俄州高中火箭队的教练,他帮助他的学生参加了一场全国比赛,该比赛包括全国800多个高中和中学队。

“比赛一年四季都在进行,挑战每年都在变化。去年的任务是制造适合特定参数的火箭,该火箭将3个生鸡蛋的有效载荷运送到850英尺的特定高度,并进行总飞行时间为43到46秒,参数紧张,比赛竞争激烈,各支球队在当地飞行以取得资格,提交分数,并且邀请前100名球队参加在弗吉尼亚州举行的全国飞行5月,比赛由航空航天领域的一些主要公司赞助,他们为参与者提供奖学金,实习机会以及其他机会,随后,优胜者将与其他竞争国际优胜者,因此是一件大事。比赛旨在在全国范围内推广STEM,并为学生展示机会。

NK5500风速仪

我们的团队在俄亥俄州,因此我们在冬季进行大部分测试,这会产生与五月份在弗吉尼亚州所经历的天气条件,温度,湿度等完全不同的天气条件。我们需要捕获的天气条件,以便我们能够资格,然后我们需要预测并考虑决赛所面临的大气条件,这对于我们的成功至关重要。天气条件之间的差异可能至少为100英尺或更多,并且团队始终位于目标高度的几英尺之内,因此,对于所有事物,数据越多越好。去年我们进入了决赛,但未能达到目标,因此,今年我们正在通过收集每次发射的天气数据来挖掘天气因素,并且我们试图基于从红茶rel部门获得的数据创建预测模型,以根据条件调整火箭。这是我们使用红est的年,到目前为止,它正在帮助我们完成任务。”

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."
