天女工程第二章,1000G 的破局与11公里的弹道。 小李的报告在桌上摊开,老张的手指停在加速度40G 那行,突然敲了敲桌面,这数不对。 他拿起笔在空白处写下公式。 竖直上抛运动,忽略空气阻力的话,最大高度 H 等于 V 二斜杠,要达到11公里,V 至少得对括号,2×9,8×11000,括回,约等于464米每秒。 小李额头冒汗,之前算错了射高对应的速度,再算加速度。 老张继续推导,轨道长50米,用 V 平方等于2AL,A 等于 V 二斜杠,等于464平方除以,约等于2153米每秒平方,差不多220G,这个数字比之前的40G翻了5倍多,220G。 钛合金弹体能扛住,小李急忙翻出材料测试数据。 电磁炮炮弹能扛5000G,220G 不算事。 老张却指向更关键的问题。 但速度提至464米每秒,弹体上的空气阻力会翻倍。 实际需要的出膛速度得接近500米每秒,加速度要到2500米每秒平方,也就是255G。 他划掉报告里的40G,重写255G。 这这才是真实的波子,之前漏算了空气阻力,现在改过了。 薄膜的压缩结构、开伞装置,都得按255G重新设计。 一、动力参数。 轨道长度50米,出膛速度500米每秒,加速度2500米每秒平方,约等于255G。 钛合金弹壳形变率小于0,1%。 磁场强度2.5特斯拉,发射电流12万。 二,弹道与覆盖。 实际射高11公里,弹体质量58公斤,薄膜展开255只过载下,钢珠卡损需加粗05毫米,弹簧弹力提升20%,确保开伞成功率100%。 漂移范围,平流层风速30公里每小时,24小时漂移约720公 三、成本与效率。 单枚弹体成本2万元。 增加结构强化材料,比原22万略涨。 单日发射量,单台装置仍保持1000枚。 且三台装置每日覆盖,1000×3×0三等于90平方公里。 漂移问题没法回避,老张指着平流层风场图。 720公里每天的漂移,意味着上午布的网,下午就会飘出目标区。 那就用动态补网。 小李迅速调整方案,每6小时发射一批,按漂移方向提前预判落点,像给渔网补窟窿。 老张点头,这才是务实的办法。 别吹定点漂浮的牛,承认会漂移,但我们能快速补网,比天幕计划的轨道薄膜靠谱。 他让小李联系西北组,第一,按255G过载重新测试薄膜压缩结构,用泡沫铝填充间隙,吸收冲击。 第二,超级电容再加两组,8组门体,抵消电流提升后的冷却时间。 第三,成 本控制在2.5万元每年内,不能超。 小李刚要走,老张又叫住他。 天蓬计划的最新宣传说,膜模糊漂移,正好。 让他们吹这个牛,我们悄悄解决漂移的补网办法,这才是真优势。 办公室的日光灯下,修正后的参数表上,255G的数字格外刺眼。 小李突然明白,天女工程的核心从不是完美的技术,而是值直面问题的务实,知道平流层会漂移,就用补网应对,知道过载高,就强化结构,知道成本要控。 就把每一分钱花在刀刃上。 他走出办公室时,手机里天蓬计划的推送还在弹,精准控制,薄膜定位误差小于1公里。 小李笑了笑,把新的测试任务发给西北组,重点测255这下的开伞同步性,下午要结果。 窗外的风掠过树梢,像在提醒,平流层从不会静止。 但只要网撒的够快,漂移再远,也能罩住该罩的地方。

Chapter 2 of the Tiannu Project: Breaking Through 1000G and an 11-Kilometer Trajectory Xiao Li's report lay spread out on the desk. Old Zhang's finger paused at the line labeled "acceleration 40G," then suddenly tapped the table. "This number is wrong." He picked up a pen and wrote a formula in the margin. For vertical projectile motion, ignoring air resistance, the maximum height H equals V squared divided by 2g. To reach 11 kilometers, V must be at least the square root of (2 × 9.8 × 11000), which is approximately 464 meters per second. Sweat beaded on Xiao Li's forehead. He had miscalculated the velocity corresponding to the height, and now acceleration needed to be recalculated. Old Zhang continued his derivation. The track length is 50 meters. Using V squared equals 2AL, A equals V squared divided by 2L, which is 464 squared divided by 100, approximately 2153 meters per second squared, roughly 220G. This number was more than five times the original 40G—220G. "Titanium alloy projectiles can withstand it," Xiao Li said quickly, flipping through material test data. "Electromagnetic cannon shells can endure 5000G, so 220G is nothing." But Old Zhang pointed to a more critical issue. "However, when the velocity reaches 464 meters per second, the air resistance on the projectile doubles. The actual required muzzle velocity needs to be close to 500 meters per second, and the acceleration must reach 2500 meters per second squared, which is 255G." He crossed out the 40G in the report and wrote 255G. "This is the real value. We omitted air resistance earlier. Now it's corrected. The membrane compression structure and the canopy deployment device must be redesigned for 255G." **First: Power Parameters** Track length: 50 meters. Muzzle velocity: 500 meters per second. Acceleration: 2500 meters per second squared, approximately 255G. Titanium alloy casing deformation rate: less than 0.1%. Magnetic field strength: 2.5 Tesla. Launch current: 120,000 amperes. **Second: Trajectory and Coverage** Actual altitude: 11 kilometers. Projectile mass: 58 kilograms. Membrane deployment: Under 255G overload, the steel ball latch needs to be thickened by 0.5 millimeters, and spring tension increased by 20% to ensure 100% canopy deployment success. Drift range: At a stratospheric wind speed of 30 kilometers per hour, 24-hour drift is approximately 720 kilometers. **Third: Cost and Efficiency** Single projectile cost: 20,000 RMB. Additional structural reinforcement materials will increase the cost slightly from the original 20,000. Daily launch volume per device: still 1,000 rounds. With three devices, daily coverage: 1,000 × 3 × 0.3 = 90 square kilometers. "The drift issue cannot be avoided," Old Zhang said, pointing to the stratospheric wind field map. "A drift of 720 kilometers per day means that a net deployed in the morning will drift out of the target area by afternoon." "Then we use dynamic net patching," Xiao Li quickly adjusted the plan. "Launch a batch every 6 hours, predict the landing points in advance based on the drift direction—like patching holes in a fishing net." Old Zhang nodded. "That's the practical approach. Don't boast about pinpoint stationary floating. Admit that drift exists, but we can patch the net quickly. That's more reliable than the orbital membrane plan of the Tianmu Project." He instructed Xiao Li to contact the Northwest Group: First, retest the membrane compression structure under 255G overload, filling gaps with aluminum foam to absorb impact. Second, add two more sets of supercapacitors—8 units total—to offset the cooling time after the current boost. Third, control the cost within 25,000 RMB per round—no exceptions. Just as Xiao Li was about to leave, Old Zhang called him back. "The latest promotion from the Tianpeng Project says their membrane has zero drift. Perfect. Let them boast about that. We'll quietly develop the patching method to solve the drift problem—that's our real advantage." Under the fluorescent office light, the revised parameter table glared with the number 255G. Suddenly, Xiao Li understood: The core of the Tiannu Project was never flawless technology, but the pragmatism of facing problems head-on. Knowing the stratosphere would drift, they used net patching. Knowing the overload would be high, they reinforced the structure. Knowing costs had to be controlled, they spent every cent where it mattered. As he walked out of the office, a push notification from the Tianpeng Project kept popping up on his phone: *Precise control, membrane positioning error less than 1 kilometer.* Xiao Li smiled and sent the new test task to the Northwest Group: *Focus on testing the canopy deployment synchronization under 255G. Results needed by afternoon.* Outside, the wind rustled through the treetops, as if reminding him that the stratosphere never stays still. But as long as the net is cast fast enough, no matter how far it drifts, it will still cover what needs to be covered.
