这次起飞的翼龙-2H 无人机是从贵阳附近起飞的,抵达河南上空后依然能提供 5 小时的滞空时间,算上来回飞行时间和预案里预留的任务冗余,整个滞空能力至少是 20 小时往上。

一个被经常问到的问题是「为什么只出动了一架」而非「多架次接力保证全时覆盖」,因为现在只有这一架,真的没有多。

这个项目中航去年年中才做出来,还在进行进一步的测试和改进,要把基站上天、信号中继、组网等各种功能全部集成在吊舱里,还要做到极高的可靠性、可用性,还要能保证能耗不高,能配合长时间滞空的任务需要,真的非常难。(初号机永远滴神!)

这次河南的灾情对这套系统可以说是第一次实战级别的检验,而相信这个项目投产以后,我们的应急航空能力也会大幅提高。如果下次有需要的话,可能起飞的就不是一架无人机,而是一个能提供全时通讯能力覆盖的机群了。

河南加油,中航加油。

Should I buy bitcoin?

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
